Well, actually you can use fqs, it's just that re-using them becomes a bit more tricky. Specifically, fq=field1:blah OR field2:blort is perfectly reasonable. However, it doesn't break things down into sub-clauses, so fq=field1:blah will create a new entry in the filtercache. And fq=field2:blort OR field1:blah will not match the first one.
It kind of depends on the query pattern whether the filtercache will be re-used, you have to take care to construct the fq clauses with re-use in mind if you want ORs.
