   </P

>&#13;    <VAR
CLASS="parameter"
>dbaddr</VAR
> - URL-style database description, with
    options (type, host, database name, port, user and password) to connect 
    to SQL database. Do not matter for built-in text files support. Format for
    <VAR
CLASS="parameter"
>dbaddr</VAR
>:
    <VAR
CLASS="literal"
>DBType:[//[DBUser[:DBPass]@]DBHost[:DBPort]]/DBName/</VAR
>.
    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 <VAR
CLASS="literal"
>unknown</VAR
> instead.
  </P
><P
>&#13;    <VAR
CLASS="parameter"
>dbmode</VAR
> - You may select the SQL database mode of
    words storage. Possible values of <VAR
CLASS="parameter"
>dbmode</VAR
> are:
    <VAR
CLASS="literal"
>single</VAR
>, <VAR
CLASS="literal"
>multi</VAR
>, <VAR
CLASS="literal"
>crc</VAR
>,
    or <VAR
CLASS="literal"
>crc-multi</VAR
>. When <VAR
CLASS="literal"
>single</VAR
> is
    specified, all words are stored in the same table. If <VAR
CLASS="literal"
>multi
    </VAR
> 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. <VAR
CLASS="literal"
>crc-multi</VAR
> uses the same storage structure
    with the "crc" mode, but also stores words in different tables depending on
    words lengths like in "multi" mode.

     In fact this function does not open a connection to the database and
     thus does not check the entered login and password. Establishing a
     connection to the database and login/password verification is done by
