>&#13;      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).
