Do not matter for built-in text files support. Format for <i><tt class="parameter">dbaddr</tt></i>: <i>DBType:[//[DBUser[:DBPass]@]DBHost[:DBPort]]/DBName/</i>. Currently supported DBType values are: mysql, pgsql, msql, solid, mssql, oracle, and ibase. Actually, it does not matter for native libraries support, but ODBC users should specify one of the supported values. If your database type is not supported, you may use <i>unknown</i> instead. </p> </dd> </dt> <dt> <span class="term"><i><tt class="parameter">dbmode</tt></i></span> <dd> <p class="para"> <i><tt class="parameter">dbmode</tt></i> - You may select the SQL database mode of words storage. Possible values of <i><tt class="parameter">dbmode</tt></i> are: <i>single</i>, <i>multi</i>, <i>crc</i>, or <i>crc-multi</i>. When <i>single</i> is specified, all words are stored in the same table. If <i>multi </i> is selected, words will be located in different tables depending of their lengths. "multi" mode is usually faster, but requires more tables in the database. If "crc" mode is selected, mnoGoSearch will store 32 bit integer word IDs calculated by CRC32 algorithm instead of words. This mode requires less disk space and it is faster comparing with "single" and "multi" modes. <i>crc-multi</i> uses the same storage structure with the "crc" mode, but also stores words in different tables depending on words lengths like in "multi" mode. </p> </dd> </dt> </dl> </p> <blockquote><p><b class="note">Note</b>: <i><tt class="parameter">dbaddr</tt></i> and <i><tt class="parameter">dbmode</tt></i> must match those used during indexing. <br /> </p></blockquote> </div> <div class="refsect1 returnvalues"> <h3 class="title">Return Values</h3> <p class="para"> Returns a mnogosearch agent identifier on success, <b><tt>FALSE</tt></b> on failure.
