<para>
|
|
Returns a mnogosearch agent identifier on success, &false; on failure. This
|
|
function creates a session with database parameters.

</para>
|
|
|
|
<para>
|
|
<parameter>dbaddr</parameter> - 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
|
|
<parameter>dbaddr</parameter>:
|
|
<literal>DBType:[//[DBUser[:DBPass]@]DBHost[:DBPort]]/DBName/</literal>.
|
|
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 <literal>unknown</literal> instead.
|
|
</para>
|
|
|
|
<para>
|
|
<parameter>dbmode</parameter> - You may select the SQL database mode of
|
|
words storage. Possible values of <parameter>dbmode</parameter> are:
|
|
<literal>single</literal>, <literal>multi</literal>, <literal>crc</literal>,
|
|
or <literal>crc-multi</literal>. When <literal>single</literal> is
|
|
specified, all words are stored in the same table. If <literal>multi
|
|
</literal> 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. <literal>crc-multi</literal> uses the same storage structure
|
|
with the "crc" mode, but also stores words in different tables depending on
|
|
words lengths like in "multi" mode.
|
|
</para>
|
|
|
|
<note>
|
|
<para>
|
|
<parameter>dbaddr</parameter> and <parameter>dbmode</parameter> must match
|
|
those used during indexing.

<para>
|
|
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
|
|
<function>udm_find</function>.
