How to modify sphinx search for standard opencart 1.5.6.4 filter?

Question

PHP

There is OpenCart 1.5.6.4, a store with 700k products and a Sphinx search engine with this module for communication. Faced with the fact that when using the Sphinx to display categories, the standard product filter stops working. I rummaged through the sources - not surprisingly, there is not a word about the filter in the category. The level of PHP proficiency does not allow rashly climbing into the finished sphinx module, so there is a big question - can someone tell me what can be poke to make the filter work? Maybe someone has already been through this event and is ready to share their experience?
