CREATE TEXT SEARCH DICTIONARY
Defines a new text search dictionary.
Synopsis
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.
