udm_alloc_agent -- Allocate mnoGoSearch session
Description
int udm_alloc_agent (string dbaddr [, stringdbmode])
udm_alloc_agent() returns mnogosearch agent identifier on success, FALSE
on error. This function creates a session with database parameters.
dbaddr - URL-style database description. Options (type, host, database
name, port, user and password) to connect to SQL database. Do not matter for built-in text files
support. Format: DBAddr DBType:[//[DBUser[:DBPass]@]DBHost[:DBPort]]/DBName/ Currently supported
DBType values are: mysql, pgsql, msql, solid, mssql, oracle, ibase. Actually, it does not matter
for native libraries support. But ODBC users should specify one of supported values. If your
database type is not supported, you may use "unknown" instead.
dbmode - You may select SQL database mode of words storage. 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 database. If "crc" mode is selected, mnoGoSearch will store 32 bit integer word IDs
calculated by CRC32 algorythm instead of words. This mode requres 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 "multi" mode.
Format: DBMode single/multi/crc/crc-multi
Note: dbaddr and dbmode must match those used during
indexing.
Note: In fact this function does not open connection to database and thus does not check
entered login and password. Actual connection to database and login/password verification is done
by udm_find().
