Subject [jira] Commented: (LUCENE-1290) Deprecate Hits
Date Tue, 20 May 2008 03:54:55 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598170#action_12598170

Otis Gospodnetic commented on LUCENE-1290:
------------------------------------------

I'm actually feeling -1-ish about this.  I don't think Hits are hurting those who are truly
concerned about performance.  Those who want performance have other API options.  But Hits
is so nice and simple, and that must be valuable to a large portion of Lucene users (think
CD searches, site searches, desktop search apps, etc., not massive distributed searches and
such).

Why can't we let Hits live?  If we are concerned about its performance, we can easily javadoc
and Wiki that.

> 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.
