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 <TT CLASS="COMMAND" >ALTER TEXT SEARCH CONFIGURATION</TT > 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 > Refer to <A HREF="textsearch.html" >Chapter 12</A > for further information. </P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN71551" ></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 configuration to be created.
