Shai Erera commented on LUCENE-1720:
------------------------------------
Hmm ... I've added the method above, and it solved the issue in one of the
tests, but revealed other issues with FilterIndexReader, like for example it
doesn't override getUniqueTermCount() and reopen() ... so maybe we need to
change the current TestFilterIndexReader to extend TestIndexReader and
override getReader() ... this looks like a separate issue, though it will block
this issue ...
A change in TestIndexReader is also required in one test which asserts that the
instance of the reader is DirectoryReader (or ReadOnlySegmentReader), but
that's easy to do by for example adding a isInstanceOf(IndexReader) method to
TestIndexReader which will be overridden in TestFilterIndexReader and
TestTimeLimitingIndexReader.

> 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.
