          Spelld server reads spell-data from a separate configuration file
          (/usr/local/mnogosearch/etc/spelld.conf by default), sorts it and stores in
          memory. With clients server communicates in two ways: to indexer all the
          data is transferred (so that indexer starts faster), from search.cgi server
          receives word to normalize and then passes over to client (search.cgi) list
          of normalized word forms. This allows fastest, compared to db and text modes
          processing of search queries (by omitting loading and sorting all the spell data).

          <b>udm_load_ispell_data()</b> function in UDM_ISPELL_TYPE_SERVER

          In fact, server is automatically used by <a href="function.udm-find.html" class="function">udm_find()</a>
          function when performing search. In case of errors, e.g. if spellserver
          is not running or invalid host indicated, there are no messages returned
          and ispell conversion does not work.
