Carl Austin commented on LUCENE-1720:
-------------------------------------
Lucene 3.3 changed scoring in TermQuery (and others?) which means that
TimeLimitedIndexReader breaks query scoring, returning all scores as 0. This is
because hash codes for the subreaders are stored and reused. Unfortunately the
getSequentialSubReaders uses a new wrapping object each time and doesn't
implement hash code in anyway, hence returning oid's. In my case I just
implemented hashcode in the TimeLimitedIndexReader, returning in.hashcode() and
this fixed the problem.

> An alternative to TimeLimitedCollector that has the following advantages:
> 1) Any reader activity can be time-limited rather than just single searches
> e.g. the document retrieve phase.
> 2) Times out faster (i.e. runaway queries such as fuzzies detected quickly
> before last "collect" stage of query processing)
> Uses new utility timeout class that is independent of IndexReader.
> Initial contribution includes a performance test class but not had time as
> yet to work up a formal Junit test.
> TimeLimitedIndexReader is coded as JDK1.5 but can easily be undone.
