You used Hits to get all that hits? Nasty man - thats we deprecated that
class - even though the JavaDoc warns you thats a major speed trap,
everyone still did it ... use a Collector.
Your right though - it shouldn't point to IndexSearcher.search(Query)
after that - it should point to IndexSearcher.search(Query, int)
Goto fix that.
