Tamás Cservenák commented on MINDEXER-14:
-----------------------------------------
Another remark: in case of IteratorSearchResult only, result.getTotalHits()
will _always_ tell the truth about the count of hits (this is NOT true for
non-iterator searches), even if the actual result set returned is limited to
1k. But frankly, do you _really_ want to process 1k of result hits? What is
your use case?
> FlatSearchResponse.totalHits = 1000 when there are in fact more

> Key: MINDEXER-14
> URL: http://jira.codehaus.org/browse/MINDEXER-14
> Project: Maven Indexer
> Issue Type: Bug
> Affects Versions: 4.0.0
> Environment: Ubuntu, JDK 6; cause of:
> https://netbeans.org/bugzilla/show_bug.cgi?id=197036
> Reporter: Jesse Glick
>
> I am running {{SearchEngine.searchFlatPaged}}. When there happen to be more
> than 1000 hits in the result, it silently returns just 1000 instead.
> Surprising behavior since I did not specify any hit limit. But this is
> {{AbstractSearchRequest.UNDEFINED_HIT_LIMIT}}, OK.
> Where it gets weirder is that if you set {{resultHitLimit}} to
> {{UNDEFINED_HIT_LIMIT}}, you still get 1000 results, contradicting the
> apparent meaning of "undefined". Further, if you set it to 999 or 1001, and
> there are a few thousand results, you get an empty result and {{totalHits}}
> of -1 or {{AbstractSearchResponse.LIMIT_EXCEEDED}} (which by the way looks
> like a constant but is not final!), which is completely different than the
> behavior for 1000.
> And passing in {{Integer.MAX_VALUE}} to begin with does not work, since then
> Lucene gets an {{OutOfMemoryError}} trying to allocate a ridiculously large
> array or similar.
> Expected behavior: by default, on an otherwise unconfigured search request,
> the indexer would return all the hits, however many that is (allocating only
> a proportional amount of memory). If I set {{resultHitLimit}} to some value,
> then that will be used - I will either get a complete set of results, or
> {{LIMIT_EXCEEDED}}.
> Workaround: set {{resultHitLimit}} to 1001, then go into a loop retrying the
> search; if -1 returned for {{totalHits}}, double the {{resultHitLimit}} and
> try again.
