Creating a table

On Windows, if you want Manticore to start at boot, you can install it as a Windows Service. You can follow the instructions in the Manticore as Windows Service guide to install Manticore as a service.

Once Manticore is installed as a service, you can start and stop it from the Control Panel or from the command line using the sc.exe command.

sc.exe start Manticore

sc.exe stop Manticore

Alternatively, if you don't install Manticore as a Windows service, you can start it from the command line by running the following command:

.\bin\searchd -c manticore.conf

This command assumes that you have the Manticore's binary and the configuration file in the current directory.

In MacOS

If Manticore is installed using HomeBrew, you can run it as a Brew service.

To start Manticore, run the following command:

brew services start manticoresearch

To stop Manticore, run the following command:

brew services stop manticoresearch

In Windows 3️⃣ Creating a table

In MacOS Data types

Manticore's data types can be split into two categories: full-text fields and attributes.

Field names in Manticore must follow these rules:

Can contain letters (a-z, A-Z), numbers (0-9), and hyphens (-)
Must start with a letter
Numbers can only appear after letters
Underscore (_) is the only allowed special character
Field names are case-insensitive

For example:

Valid field names: title, product_id, user_name_2
Invalid field names: 2title, -price, user@name

Full-text fields:

can be indexed with natural language processing algorithms, therefore can be searched for keywords
cannot be used for sorting or grouping
original document's content can be retrieved
original document's content can be used for highlighting

Full-text fields are represented by the data type text. All other data types are called "attributes".

Attributes are non-full-text values associated with each document that can be used to perform non-full-text filtering, sorting and grouping during a search.

It is often desired to process full-text search results based not only on matching document ID and its rank, but also on a number of other per-document values. For example, one might need to sort news search results by date and then relevance, or search through products within a specified price range, or limit a blog search to posts made by selected users, or group results by month. To do this efficiently, Manticore enables not only full-text fields, but also additional attributes to be added to each document. These attributes can be used to filter, sort, or group full-text matches, or to search only by attributes.

The attributes, unlike full-text fields, are not full-text indexed. They are stored in the table, but it is not possible to search them as full-text.

A good example for attributes would be a forum posts table. Assume that only the title and content fields need to be full-text searchable - but that sometimes it is also required to limit search to a certain author or a sub-forum (i.e., search only those rows that have some specific values of author_id or forum_id); or to sort matches by post_date column; or to group matching posts by month of the post_date and calculate per-group match counts.

    stored_fields = title, content

    rt_attr_uint = author_id
    rt_attr_uint = forum_id

Manticore supports two types of attribute storages:

row-wise - traditional storage available in Manticore Search out of the box
columnar - provided by Manticore Columnar Library

As can be understood from their names, they store data differently. The traditional row-wise storage:

stores attributes uncompressed
all attributes of the same document are stored in one row close to each other
rows are stored one by one
accessing attributes is basically done by just multiplying the row ID by the stride (length of a single vector) and getting the requested attribute from the calculated memory location. It gives very low random access latency.
attributes have to be in memory to get acceptable performance, otherwise due to the row-wise nature of the storage Manticore may have to read from disk too much unneeded data which is in many cases suboptimal.

With the columnar storage:

each attribute is stored independently of all other attributes in its separate "column"
storage is split into blocks of 65536 entries
the blocks are stored compressed. This often allows storing just a few distinct values instead of storing all of them like in the row-wise storage. High compression ratio allows reading from disk faster and makes the memory requirement much lower
when data is indexed, storage scheme is selected for each block independently. For example, if all values in a block are the same, it gets "const" storage and only one value is stored for the whole block. If there are less than 256 unique values per block, it gets "table" storage and stores indexes to a table of values instead of the values themselves
search in a block can be early rejected if it's clear the requested value is not present in the block.

The columnar storage was designed to handle large data volume that does not fit into RAM, so the recommendations are:

if you have enough memory for all your attributes you will benefit from the row-wise storage
otherwise, the columnar storage can still give you decent performance with a much lower memory footprint which will allow you to store much more documents in your table

The traditional row-wise storage is the default, so if you want everything to be stored in a row-wise fashion, you don't need to do anything when you create a table.

To enable the columnar storage you need to:

specify engine='columnar' in CREATE TABLE to make all attributes of the table columnar. Then, if you want to keep a specific attribute row-wise, you need to add engine='rowwise' when you declare it. For example:
```
create table tbl(title text, type int, price float engine='rowwise') engine='columnar'
```

specify engine='columnar' for a specific attribute in CREATE TABLE to make it columnar. For example:

create table tbl(title text, type int, price float engine='columnar');

create table tbl(title text, type int, price float engine='columnar') engine='rowwise';

in the plain mode you need to list attributes you want to be columnar in columnar_attrs.

Below is the list of data types supported by Manticore Search:

The document identifier is a mandatory attribute that must be a unique 64-bit unsigned integer. Document IDs can be explicitly specified when creating a table, but they are always enabled even if not specified. Document IDs cannot be updated.

When you create a table, you can specify ID explicitly, but regardless of the data type you use, it will always behave as described above - stored as unsigned 64-bit but exposed as signed 64-bit integer.

mysql> CREATE TABLE tbl(id bigint, content text);
DESC tbl;
+---------+--------+----------------+
| Field   | Type   | Properties     |
+---------+--------+----------------+
| id      | bigint |                |
| content | text   | indexed stored |
+---------+--------+----------------+
2 rows in set (0.00 sec)

You can also omit specifying ID at all, it will be enabled automatically.

mysql> CREATE TABLE tbl(content text);
DESC tbl;
+---------+--------+----------------+
| Field   | Type   | Properties     |
+---------+--------+----------------+
| id      | bigint |                |
| content | text   | indexed stored |
+---------+--------+----------------+
2 rows in set (0.00 sec)

When working with document IDs, it's important to know that they are stored internally as unsigned 64-bit integers but are exposed as signed 64-bit integers in queries and results. This means:

IDs greater than 2^63-1 will appear as negative numbers.
When filtering by such large IDs, you must use their signed representation.
Use the UINT64() function to view the actual unsigned value.

For example, let's create a table and insert some values around 2^63:

mysql> create table t(id_text string);
Query OK, 0 rows affected (0.01 sec)

mysql> insert into t values(9223372036854775807, '2 ^ 63 - 1'),(9223372036854775808, '2 ^ 63');
Query OK, 2 rows affected (0.00 sec)

Some IDs appear as negative numbers in the results because they exceed 2^63-1. However, using UINT64(id) can reveal their actual unsigned values:

mysql> select *, uint64(id) from t;
+----------------------+------------+---------------------+
| id                   | id_text    | uint64(id)          |
+----------------------+------------+---------------------+
|  9223372036854775807 | 2 ^ 63 - 1 | 9223372036854775807 |
| -9223372036854775808 | 2 ^ 63     | 9223372036854775808 |
+----------------------+------------+---------------------+
2 rows in set (0.00 sec)
--- 2 out of 2 results in 0ms ---

For querying documents with IDs less than 2^63, you can use the unsigned value directly:

mysql> select * from t where id = 9223372036854775807;
+---------------------+------------+
| id                  | id_text    |
+---------------------+------------+
| 9223372036854775807 | 2 ^ 63 - 1 |
+---------------------+------------+
1 row in set (0.00 sec)
--- 1 out of 1 results in 0ms ---

However, for IDs starting from 2^63, you need to use the signed value:

mysql> select * from t where id = -9223372036854775808;
+----------------------+---------+
| id                   | id_text |
+----------------------+---------+
| -9223372036854775808 | 2 ^ 63  |
+----------------------+---------+
1 row in set (0.00 sec)
--- 1 out of 1 results in 0ms ---

If you use an unsigned value instead, you will get an error:

mysql> select * from t where id = 9223372036854775808;
ERROR 1064 (42000): number 9223372036854775808 is out of range [-9223372036854775808..9223372036854775807]

Values that do not fit within 64 bits will trigger a similar error:

mysql> select * from t where id = -9223372036854775809;
ERROR 1064 (42000): number -9223372036854775809 is out of range [-9223372036854775808..9223372036854775807]

General syntax:

string|text [stored|attribute] [indexed]

Properties:

indexed - full-text indexed (can be used in full-text queries)
stored - stored in a docstore (stored on disk, not in RAM, lazy read)
attribute - makes it a string attribute (can sort/group by it)

Specifying at least one property overrides all the default ones (see below), i.e., if you decide to use a custom combination of properties, you need to list all the properties you want.

No properties specified:

string and text are aliases, but if you don't specify any properties, they by default mean different things:

just string by default means attribute (see details below).
just text by default means stored + indexed (see details below).

The text (just text or text/string indexed) data type forms the full-text part of the table. Text fields are indexed and can be searched for keywords.

Text is passed through an analyzer pipeline that converts the text to words, applies morphology transformations, etc. Eventually, a full-text table (a special data structure that enables quick searches for a keyword) gets built from that text.

Full-text fields can only be used in the MATCH() clause and cannot be used for sorting or aggregation. Words are stored in an inverted index along with references to the fields they belong to and positions in the field. This allows searching a word inside each field and using advanced operators like proximity. By default, the original text of the fields is both indexed and stored in document storage. It means that the original text can be returned with the query results and used in search result highlighting.

Unlike full-text fields, string attributes (just string or string/text attribute) are stored as they are received and cannot be used in full-text searches. Instead, they are returned in results, can be used in the WHERE clause for comparison filtering or REGEX, and can be used for sorting and aggregation. In general, it's not recommended to store large texts in string attributes, but use string attributes for metadata like names, titles, tags, keys.

If you want to also index the string attribute, you can specify both as string attribute indexed. It will allow full-text searching and works as an attribute.

Manticore doesn't have a dedicated field type for binary data, but you can store it safely by using base64 encoding and the text stored or string stored field types (which are synonyms). If you don't encode the binary data, parts of it may get lost — for example, Manticore trims the end of a string if it encounters a null-byte.

Here is an example where we encode the ls command using base64, store it in Manticore, and then decode it to verify that the MD5 checksum remains unchanged:

Integers can be stored in shorter sizes than 32-bit by specifying a bit count. For example, if we want to store a numeric value which we know is not going to be bigger than 8, the type can be defined as bit(3). Bitcount integers perform slower than the full-size ones, but they require less RAM. They are saved in 32-bit chunks, so in order to save space, they should be grouped at the end of attribute definitions (otherwise a bitcount integer between 2 full-size integers will occupy 32 bits as well).

The timestamp type represents Unix timestamps, which are stored as 32-bit integers. Unlike basic integers, the timestamp type allows the use of time and date functions. Conversion from string values follows these rules:

Numbers without delimiters, at least 10 characters long, are converted to timestamps as is.
%Y-%m-%dT%H:%M:%E*S%Z
%Y-%m-%d'T'%H:%M:%S%Z
%Y-%m-%dT%H:%M:%E*S
%Y-%m-%dT%H:%M:%s
%Y-%m-%dT%H:%M
%Y-%m-%dT%H
%Y-%m-%d
%Y-%m
%Y

The meanings of these conversion specifiers are detailed in the strptime manual, except for %E*S, which stands for milliseconds.

Note that auto-conversion of timestamps is not supported in plain tables.

Unlike integer types, comparing two floating-point numbers for equality is not recommended due to potential rounding errors. A more reliable approach is to use a near-equal comparison, by checking the absolute error margin.

Another alternative, which can also be used to perform IN(attr,val1,val2,val3) is to compare floats as integers by choosing a multiplier factor and convert the floats to integers in operations. The following example illustrates modifying IN(attr,2.0,2.5,3.5) to work with integer values.

Float values in Manticore are displayed with precision to ensure they reflect the exact stored value. This approach was introduced to prevent precision loss, especially for cases like geographical coordinates, where rounding to 6 decimal places caused inaccuracies.

Now, Manticore first outputs a number with 6 digits, then parses and compares it to the original value. If they don't match, additional digits are added until they do.

For example, if a float value was inserted as 19.45, Manticore will display it as 19.450001 to accurately represent the stored value.

This data type allows for the storage of JSON objects, which is particularly useful for handling schema-less data. When defining JSON values, ensure that the opening and closing curly braces { and } are included for objects, or square brackets [ and ] for arrays. While JSON is not supported by columnar storage, it can be stored in traditional row-wise storage. It's worth noting that both storage types can be combined within the same table.

Float vector attributes allow storing variable-length lists of floats, primarily used for machine learning applications and similarity searches. This type differs from multi-valued attributes (MVAs) in several important ways:

Preserves the exact order of values (unlike MVAs which may reorder)
Retains duplicate values (unlike MVAs which deduplicate)
No additional processing during insertion (unlike MVAs which sort and deduplicate)

Currently only supported in real-time tables
Can only be utilized in KNN (k-nearest neighbor) searches
Not supported in plain tables or other functions/expressions
When used with KNN settings, you cannot UPDATE float_vector values. Use REPLACE instead
When used without KNN settings, you can UPDATE float_vector values
Float vectors cannot be used in regular filters or sorting
The only way to filter by float_vector values is through vector search operations (KNN)

Image embeddings for similarity search
Text embeddings for semantic search
Feature vectors for machine learning
Recommendation system vectors

When grouping by a multi-value attribute, a document will contribute to as many groups as there are different values associated with that document. For instance, if a collection contains exactly one document having a 'product_codes' multi-value attribute with values 5, 7, and 11, grouping on 'product_codes' will produce 3 groups with COUNT(*)equal to 1 and GROUPBY() key values of 5, 7, and 11, respectively. Also, note that grouping by multi-value attributes may lead to duplicate documents in the result set because each document can participate in many groups.

When you use the columnar storage you can specify the following properties for the attributes.

By default, Manticore Columnar storage stores all attributes in a columnar fashion, as well as in a special docstore row by row. This enables fast execution of queries like SELECT * FROM ..., especially when fetching a large number of records at once. However, if you are sure that you do not need it or wish to save disk space, you can disable it by specifying fast_fetch='0' when creating a table or (if you are defining a table in a config) by using columnar_no_fast_fetch as shown in the following example.
