)
</pre></div><div class="refsect1" id="id-1.9.3.88.5"><h2>Description</h2><p>
<code class="command">CREATE TEXT SEARCH CONFIGURATION</code> creates a new text
search configuration. A text search configuration specifies a text
search parser that can divide a string into tokens, plus dictionaries
that can be used to determine which tokens are of interest for searching.
</p><p>
If only the parser is specified, then the new text search configuration
initially has no mappings from token types to dictionaries, and therefore
will ignore all words. Subsequent <code class="command">ALTER TEXT SEARCH
CONFIGURATION</code> commands must be used to create mappings to
make the configuration useful. Alternatively, an existing text search
configuration can be copied.
</p><p>
If a schema name is given then the text search configuration is created in
the specified schema. Otherwise it is created in the current schema.
</p><p>
The user who defines a text search configuration becomes its owner.
</p><p>

The <code class="literal">PARSER</code> and <code class="literal">COPY</code> options are mutually
exclusive, because when an existing configuration is copied, its
parser selection is copied too.
