Michael Busch commented on LUCENE-1290:
---------------------------------------
Otis,
what do you think are the advantages of Hits over the TopDocCollector/TopDocs
approach? If you look at the demo in this patch then you'll notice that I
actually didn't make many changes and that it's just as easy to do paging
without Hits.
I think almost everybody who wants to have a decent control over performance
and memory consumption during hit collection should use a HitCollector.
Also, removing Hits will simplify the search methods and we'll have some APIs
less to support :).

> URL: https://issues.apache.org/jira/browse/LUCENE-1290
> Project: Lucene - Java
> Issue Type: Task
> Components: Search
> Reporter: Michael Busch
> Assignee: Michael Busch
> Priority: Minor
> Fix For: 2.4
>
> Attachments: lucene-1290.patch
>
>
> 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.
