NAME
CREATE_TEXT_SEARCH_DICTIONARY - define a new text search dictionarySYNOPSIS
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, 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 );
