Searching for a value of an attribute of Type:Float without units doesn't return pages with that value that do have units. E.g. if attribute values are 42 (no value), 42 km, and 42 miles; then searching for 42 only finds the first one. SpecialSearchTriple's searchAttributes() always queries on unit, even if unit is blank. Maybe it should treat a blank unit as NULL unit so it doesn't search on it. This may only be true for SearchTriple, but I think AskSpecial has issues also. (If an attribute is of a type that does support unit conversions, then I believe leaving off the unit triggers the default unit conversion. I think that's reasonable behavior.)
Special:SearchTriple is about to be rewritten, so we have to wait which new specials appear and which problems they have. In general, they are likely to behave much like <ask> and its special, since all unit handling is now taken care of by SMWDataValue which is passed on for searching a value -- the caller no longer decides which untis are passed, but merely generates an SMWDataValue which does this. I think this closes this bug.
