Real Time indexes in Sphinx. How to work with linked tables?

Question

PHP

Goodnight.
I've been struggling with real time indexes for a day now.
At the moment the project works on delta indexes. But I want faster updates.
I don't know what to do with the primary key, since more than 5 tables are linked to add in the query.
Generate random number? Sampling all the same goes on a heap of parameters.
Also, it is not possible to add an entry:

$connection = mysql_connect("127.0.0.1:9306") or die ("Couldn't connect to server.");
$db = mysql_query("INSERT INTO `rtIndex` (`id`, `Title`, `Description`) VALUES (1, '', '');", $connection);

Although through SSH the index can be filled. Through php even it is possible to search in this index.

Answer 1

Perhaps the problem is in quotes, run this query through the console
