The search engine is part of the phpBB software package so we have no control over it, but I'd say there is a fundamental mistake in it.
Normally, if you put in "set phrase" without quotation marks and you have the radio button "Search for all terms or use query as entered" selected, a search engine should only give you posts with both "set" and "phrase" in it. (If you enter "set phrase" in quotation marks the engine should only return instances where the two words are together in that order.)
If you enter "set phrase" without quotation marks and you have the radio button "Search for any terms" selected, a normal search engine should give you posts in which either "set" or "phrase" appear.
For some reason, this version of the phpBB search engine gives the equivalent of "Search for any terms" regardless of which button you elect.
In short, it's frustrating Saoirse but it is the way the engine is set up and I am not sure how to fix it.
