Definition PG 18
CREATE TEXT SEARCH DICTIONARY name ( TEMPLATE = template [, option = value [, ... ]] )
Description
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 for further information.
Parameters
nameThe name of the text search dictionary to be created. The name can be schema-qualified.
templateThe name of the text search template that will define the basic behavior of this dictionary.
optionThe name of a template-specific option to be set for this dictionary.
valueThe 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.
