Ahhh, you need to look down another few lines. When you specify fq, there should be a section of the debug output like <arr name="filter_queries"> . . . </arr>
where the array is the parsed form of the filter queries. I was thinking about comparing that with the parsed form of the "q" parameter in the non-filter case to see what insight one could gain from that. But there's already one difference, when you use *, you get <str name="parsedquery">ID:*</str> Is it possible that you have some documents that do NOT have an ID field? try *:* rather than just *. I'm guessing that your default search field is ID and you have some documents without an ID field. Not a good guess if ID is your <uniqueKey> though...... Try q=*:* -ID:* and see if you get 31 docs. Also note that if you _have_ specified ID as your <uniqueKey> _but_ you didn't re-index afterwards (actually, I'd blow away the entire <solrhome>/data directory and restart) you may have stale data in there that allowed documents to exist that do not have uniqueKey fields.....
