<title>Description</title>
<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.
</para>
<para>
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.
</para>
<para>
The user who defines a text search dictionary becomes its owner.
