CREATE TEXT SEARCH DICTIONARY <em class="replaceable"><code>name</code></em> (
TEMPLATE = <em class="replaceable"><code>template</code></em>
[, <em class="replaceable"><code>option</code></em> = <em class="replaceable"><code>value</code></em> [, ... ]]
)
</pre></div><div class="refsect1" id="id-1.9.3.89.5"><h2>Description</h2><p>
<code class="command">CREATE TEXT SEARCH DICTIONARY</code> 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.
</p><p>
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.
</p><p>
The user who defines a text search dictionary becomes its owner.
