   (PHP 4 >= 4.0.5)
   udm_alloc_agent -- Allocate mnoGoSearch session

Description

   resource udm_alloc_agent ( string dbaddr [, string dbmode])

   Returns a mnogosearch agent identifier on success, FALSE on failure.
   This function creates a session with database parameters.

   dbaddr - 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 dbaddr:
   DBType:[//[DBUser[:DBPass]@]DBHost[:DBPort]]/DBName/. 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 unknown instead.

   dbmode - You may select the SQL database mode of words storage.
   Possible values of dbmode are: single, multi, crc, or crc-multi. When
   single is specified, all words are stored in the same table. If multi
   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. crc-multi uses the same storage
   structure with the "crc" mode, but also stores words in different
   tables depending on words lengths like in "multi" mode.

     Note: dbaddr and dbmode must match those used during indexing.

     Note: 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 udm_find().
