CREATE TEXT SEARCH DICTIONARY <em class="replaceable"><code>name</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.
</p><p>
Refer to <a class="xref" href="textsearch.html" title="Chapter 12. Full Text Search">Chapter 12</a> for further information.

The name of the text search template that will define the basic

The name of a template-specific option to be set for this dictionary.
</p></dd><dt><span class="term"><em class="replaceable"><code>value</code></em></span></dt><dd><p>
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).
</p></dd></dl></div><p>
The options can appear in any order.
</p></div><div class="refsect1" id="id-1.9.3.89.7"><h2>Examples</h2><p>
The following example command creates a Snowball-based dictionary
with a nonstandard list of stop words.
