<para>
|
|
<command>CREATE TEXT SEARCH DICTIONARY</command> 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.
