<para><function>udm_alloc_agent</function> returns mnogosearch agent
|
|
identifier on success, &false; on error. This function creates a
|
|
session with database parameters.

</para>
|
|
|
|
<para>
|
|
<parameter>dbaddr</parameter> - 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.
|
|
</para>
|
|
|
|
<para>
|
|
<parameter>dbmode</parameter> - 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</para>
|
|
|

<note>
|
|
<para>
|
|
<parameter>dbaddr</parameter> and <parameter>dbmode</parameter> must match
|
|
those used during indexing.

<para>

|
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 <function>udm_find</function>.
