The Hits class has several drawbacks as pointed out in
LUCENE-954.
The other search APIs that use TopDocCollector and TopDocs should be used instead.
This patch:
- deprecates org/apache/lucene/search/Hits, Hit, and HitIterator, as well as
the Searcher.search( * ) methods which return a Hits Object.
- removes all references to Hits from the core and uses TopDocs and ScoreDoc
instead
- Changes the demo SearchFiles: adds the two modes 'paging search' and 'streaming search',
each of which demonstrating a different way of using the search APIs. The former
uses TopDocs and a TopDocCollector, the latter a custom HitCollector implementation.
- Updates the online tutorial that descibes the demo.
All tests pass.
