udm_alloc_agent — Allocate mnoGoSearch session
$dbaddr
[, string $dbmode
] ) : resourceAllocate a mnoGoSearch session.
dbaddr
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
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.
Hinweis:
dbaddranddbmodemust match those used during indexing.
Returns a mnogosearch agent identifier on success, FALSE on failure. This
function creates a session with database parameters.
Hinweis:
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().
