Manticore Search Manual: Creating a table

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

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

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 data type text. All the 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 search.

It is often desired to process full-text search results based not only on matching document ID and its rank, but on a number of other per-document values as well. For instance, one might need to sort news search results by date and then relevance, or search through products within specified price range, or limit blog search to posts made by selected users, or group results by month. To do that efficiently, Manticore enables not only full-text fields, but additional attributes to each document. It's then possible to use them to filter, sort, or group full-text matches or 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 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 (ie. 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.

    # when configuring fields via config, they are indexed (and not stored) by default
    rt_field = title
    rt_field = content

    # this option needs to be specified for the field to be stored
    stored_fields = title, content

    rt_attr_uint = author_id
    rt_attr_uint = forum_id
    rt_attr_timestamp = post_date

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 rowid by 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 unneded data which is in many cases suboptimal.

With the columnar storage:

each attribute is stored independently from all other attributes in its separate "column"
storage is split into blocks of 65536 entries
the blocks are stored compressed. This often allows to store just a few distinct values instead of storing all of them like in the row-wise storage. High compression ratio allows to read 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 much lower memory footprint which will allow you to store much more documents in your table

The traditional row-wise storage is 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. It must be a unique, signed 64-bit integer. While the document ID can be specified explicitly, it is still enabled even if not specified. Document IDs cannot be UPDATE'ed.

‹›

Explicit ID
Implicit ID

📋

When you create a table you can specify ID explicitly, but no matter what datatype you use it will be always as said previously - signed 64-bit integer.

CREATE TABLE tbl(id bigint, content text);
DESC tbl;

2 rows in set (0.00 sec)

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 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 means different things:

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

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 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 and positions in the field. This allows to search a word inside each field and to use 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 it can be used in search result highlighting.

Fields are named, and you can limit your searches to a single field (e.g. search through "title" only) or a subset of fields (eg. to "title" and "abstract" only). Manticore table format generally supports up to 256 full-text fields.

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, they can be used in WHERE clause for comparison filtering or REGEX and they 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 want to also index the string attribute, can specify both as string attribute indexed. Will allow full-text searching, and works as an attribute.

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 attributes definitions (otherwise a bitcount integer between 2 full-size integers will occupy 32 bits as well).

When grouping by multi-value attribute, a document will contribute to as many groups as there are different values associated with that document. For instance, if the collection contains exactly 1 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 might 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 not only in columnar fashion, but in a special docstore row by row which enables fast execution of queries like SELECT * FROM ... especially when you are fetching lots of records at once. But if you are sure you don't need it or want to save disk space you can disable it by specifying fast_fetch='0' when you create a table or (if you are defining a table in a config) use columnar_no_fast_fetch as shown in the following example.
