<parameter>var</parameter> - parameter, indicating the source for ispell data. May have the following values:
</para>
<note>
<para>
It is recommended to load ispell data from files, since in mnogosearch 3.1.10 it is the fastest. In later versions
it is planned to optimize loading in UDM_ISPELL_TYPE_DB mode as well, so you just try several modes to find the best for you.
After using this function to free memory allocated for ispell data, please use
<function>udm_free_ispell_data</function>, even if you use UDM_ISPELL_TYPE_SERVER mode.
</para>
<para>
The fastest mode is UDM_ISPELL_TYPE_SERVER. UDM_ISPELL_TYPE_TEXT is slower
and UDM_ISPELL_TYPE_DB is the slowest. The above pattern is true for mnoGoSearch 3.1.10 - 3.1.11.
It is planned to speed up DB mode in future versions and it is going to be faster than TEXT mode.

<para>
UDM_ISPELL_TYPE_SERVER - enables spell server support. <parameter>val1</parameter> parameter indicates
address of the host running spell server. <parameter>val2</parameter> is not used yet, but
in future releases it is going to indicate number of port used by spell server.
<parameter>flag</parameter> parameter in this case is not needed since ispell data is stored
on spellserver already sorted.

<para>
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).
</para>
<para>
<function>udm_load_ispell_data</function> function in UDM_ISPELL_TYPE_SERVER mode does not
actually load ispell data, but only defines server address. In fact, server is automatically used
by <function>udm_find</function> 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.
</para>
<note>
This function is available in mnoGoSearch 3.1.12 or later.
