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.
