Changing Sphinx maximum query length

Question

I'm using Sphinx 2.0.4 with PHP with the extended match mode enabled. When I try to use the Sphinx query language, I can only get results if I use 10 words or less. For example, if I searched for something like a | b it will work just fine, but if I search for a | b | c | d | e | f | g | h | i | j | k it will always return no results, even if there are matches. Anyone know of a setting to increase this limit? I poked around in the config file but the changes I made didn't seem to change anything.

Do you use the php API and did you check the sphinx log? I have no trouble searching with 11+ words — Nin

Are you sure that is the issue? I've used queries much longer than that (eg having over 100 or'ed keywords), that work just fine.

In fact just tried...

select * from sample8 where match('one | two | three | four | five | six | seven | eight | nine | ten | eleven | twelve');
<SNIP>
20 rows in set (0.28 sec)

select * from sample8 where match('a | b | c | d | e | f | g | h | i | j | k');
<SNIP>
20 rows in set (1.14 sec)

Suggest posting an actual REAL query tha fails, rather than a fake one.
