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 Manticoresc.exe stop ManticoreAlternatively, 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.confThis command assumes that you have the Manticore's binary and the configuration file in the current directory.
Manticore's data types can be split into two categories: 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 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.

var searchResponse = searchApi.Search(searchRequest);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 addengine='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 inCREATE TABLEto make it columnar. For example:create table tbl(title text, type int, price float engine='columnar');or
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, and document IDs must be unique 64-bit unsigned integers. Document IDs can be explicitly specified, but if not, they are still enabled. Document IDs cannot be updated. Note that when retrieving document IDs, they are treated as signed 64-bit integers, which means they may be negative. Use the UINT64() function to cast them to unsigned 64-bit integers if necessary.
- Explicit ID
- Implicit ID
When you create a table, you can specify ID explicitly, but no matter what data type you use, it will be always as said previously - a signed 64-bit integer.
CREATE TABLE tbl(id bigint, content text);
DESC tbl;You can also omit specifying ID at all, it will be enabled automatically.
CREATE TABLE tbl(content text);

+---------+--------+----------------+
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 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
stringby default meansattribute(see details below). - just
textby default meansstored+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.

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.

}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).

searchResponse = searchApi.search(searchRequest);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.
- RT mode
- Plain mode
create table t(a int, b int fast_fetch='0') engine='columnar'; desc t;source min {
type = mysql
sql_host = localhost
sql_user = test
sql_pass =
sql_db = test
sql_query = select 1, 1 a, 1 b
sql_attr_uint = a
sql_attr_uint = b
}
table tbl {
path = tbl/col
source = min
columnar_attrs = *
columnar_no_fast_fetch = b
