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.

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.
