CREATE_TEXT_SEARCH_DICTIONARY(7) define a new text search dictionary

SYNOPSIS


CREATE TEXT SEARCH DICTIONARY name (
TEMPLATE = template
[, option = value [, ... ]]
)

DESCRIPTION


Note

The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

CREATE TEXT SEARCH DICTIONARY creates a new text search dictionary. A text search dictionary specifies a way of recognizing interesting or uninteresting words for searching. A dictionary depends on a text search template, which specifies the functions that actually perform the work. Typically the dictionary provides some options that control the detailed behavior of the template's functions.

If a schema name is given then the text search dictionary is created in the specified schema. Otherwise it is created in the current schema.

The user who defines a text search dictionary becomes its owner.

Refer to Chapter 12, Full Text Search, in the documentation for further information.

PARAMETERS

name

The name of the text search dictionary to be created. The name can be schema-qualified.

template

The name of the text search template that will define the basic behavior of this dictionary.

option

The name of a template-specific option to be set for this dictionary.

value

The value to use for a template-specific option. If the value is not a simple identifier or number, it must be quoted (but you can always quote it, if you wish).

The options can appear in any order.

EXAMPLES

The following example command creates a Snowball-based dictionary with a nonstandard list of stop words.

CREATE TEXT SEARCH DICTIONARY my_russian (
    template = snowball,
    language = russian,
    stopwords = myrussian
);

COMPATIBILITY

There is no CREATE TEXT SEARCH DICTIONARY statement in the SQL standard.
