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 HREF="textsearch.html" >Chapter 12</A > for further information. </P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN71609" ></A ><H2 >Parameters</H2 ><P ></P ><DIV CLASS="VARIABLELIST" ><DL ><DT ><TT CLASS="REPLACEABLE" ><I >name</I ></TT ></DT ><DD ><P > The name of the text search dictionary to be created.
