Is there a good way to cancel a search? I mean e.g. after 10 seconds or if the user changed his mind and wants to start another query. Till now I didn't have a query that took longer than 10 secs, but this can happen easily when the network connection is very slow or something like that.
I thought about starting the search in a thread and stop it if needed. But this will result in an undefined state and doesn't seem to be a good approach.

The problem is that you get unordered (or rather index order) results from a HitCollector, not ordered by score or any sort. To get the highest 100 docs by score, you normally need to see *all* the hits.
