Subject [jira] Updated: (LUCENE-1290) Deprecate Hits
Date Fri, 23 May 2008 18:55:56 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-1290?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Busch updated LUCENE-1290:
----------------------------------

    Attachment: lucene-1290.patch

Beefed up doPagingSearch() in the SearchFiles demo.
No It collects enough results for the first 5 result pages.
If the user wants to skip beyond the 5th page, then
the query is reexecuted to collect all hits, similar to 
Google. The user can now also page back or jump
directly to a page number.

I'm going to commit this patch now.

> 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.
