PolarDB:CREATE 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.

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).

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
    );
