Subject [jira] Commented: (LUCENE-1290) Deprecate Hits
Date Tue, 20 May 2008 21:12:55 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598471#action_12598471

Christian Kohlschütter commented on LUCENE-1290:
------------------------------------------------

Michael,

the current implementation of Hits certainly has its deficiencies, but represents a very simple
way to retrieve documents from Lucene. As long as there is no real replacement, I simply do
not a reason to deprecate it.

A replacement could be an API which allows something like:

for(Iterator<ScoreDoc> it = searcher.iterator(query); it.hasNext(); ) {
  (...)
  if (...) break;
}

> 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.
