I noticed some minor bugs in the original PR #927 that this PR should fix:
- When a timeout is set, we would no longer catch
`CollectionTerminatedException`.
- I added randomization to `LuceneTestCase` to randomly set a timeout, it
would have caught the above bug.
- Fixed visibility of `TimeLimitingBulkScorer`.
Before we were checking the number of vectors in the segment against the total
number of documents in IndexReader. This meant FieldExistsQuery would not
rewrite to MatchAllDocsQuery when there were multiple segments.
Instead of collecting hit-by-hit using a `LeafCollector`, we break down the
search by instantiating a weight, creating scorers, and checking the underlying
iterator. If it is backed by a `BitSet`, we directly update the reference (as
we won't be editing the `Bits`). Else we can create a new `BitSet` from the
iterator using `BitSet.of`.
The test used to leave hanging threads behind following a failure. Also one method was executing two different tests. I split the existing method into two and I am now leveraging setup and teardown to properly close all the resources both when the tests succeed as well as whey they fail.
As suggested by @zhaih on #950, we could support more cases in
`BooleanWeight#count`. This PR adds support for these cases specifically:
- Pure disjunctions where only one clause has a non-zero count.
- Pure disjunctions where one clause matches all docs.
- Negations where positive clauses match all docs (pure negation).
- Negations where positive clauses match no docs.
- Negations where negative clauses match no docs.
- Negations where negative clauses match all docs.
