Before I raise a JIRA, I thought I'd see what people think. Didn't see anything like this on a quick search of the JIRAs:
A query like q=*:*&hl=on&..... doesn't attempt to highlight anything, as well it shouldn't. But q=field1:*&hl=on&... does try to highlight. Of course it highlights every last term in the highlight fields, and is also very slow. Re-forming the query as q=*:*&fq=field1:*&hl=on&.... gets around the problem and is a better query anyway, but it still seems like trying to highlight in the above case is wrong. Worth a JIRA? Erick
