The search is case insensitive.<br />
All words must be separated by spaces.
Do not seperate words using . or _ or -, sphinx will match a space against those automatically.<br />
Putting | between words makes any of those words optional.<br />
Putting << between words makes the word on the left have to be before the word on the right.<br />
Putting - or ! in front of a word makes that word excluded. Do not add a space between the - or ! and the word.<br />
Quoting all the words using " will look for an exact match.<br />
Putting ^ at the start will limit searches to releases that start with that word.<br />
Putting $ at the end will limit searches to releases that end with that word.<br />
Putting a * after a word will do a partial word search. ie: fish* will match fishing.<br />
If your search is only words seperated by spaces, all those words will be mandatory, the order of the words is not important.<br />
You can enclose words using paranthesis. ie: (^game*|^dex*)s03*(x264<&lt;nogrp$)<br />
You can combine some of these rules, but not all.<br />';
