I have a problem with Sphinx 2.2.11, I have a large indexes, when I set a limit greather than 13 elements, I don't receive any results. I think that the problem is due to a limit on packet size. I have just inserted in my sphinx.conf file the properties max_packet_size and mem_limit, but it still doesn't work even if I set limit to 14 elements. So how can I resolve it?
UPDATE
Here my configuration: sphinx.conf
