Michael Busch commented on LUCENE-1290:
---------------------------------------

{quote}
The HitCollerctor and Iterator approach only supports forward displaying of 
results.
{quote}

Even if you want to show results 100-200, then you still need to sort at least 
200 results, also Hits needs to, it doesn't do any magic. Then you can as well 
keep the ScoreDoc[] array to page back.
Please take a look at the patch and the new demo code, that will help you 
understand how Hits and TopDocCollector/TopDocs (which is called from Hits) 
work.

{quote}
The HitCollector callback is called in index order (or in any other, 
non-deterministic order), whereas the results in Hits are sorted (by relevance 
or any given Sort order).
{quote}

Hits uses TopDocCollector/TopDocs for sorting. The same can be achieved using 
those APIs, which Searcher offers, directly. Please take a look at the patch. I 
replaced a lot of usages of Hits in the test cases with the TopDocs APIs. In 
most cases this was a one line change.

> 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.
