Can you open an issue, null should be handled like an empty DocIdSet? This
seems to be a bug in CachingWrapperFilter.
To go around this, don’t return null, and instead return the constant
DocIdSet.EMPTY_DOCIDSET. This is the preferable solution and maybe we will
change this in Lucene 4.0, to no
Hi,
I am testing some ranking methods with /contrib/benchmark/quality package,
and i was wondering if there is a simple way of building a precision-recall
graph with the info gathered(maybe QualityStats.RecallPoint).
Thanks

Personally I use the generated submission.txt, and run it thru
trec_eval to get all numbers.
by default, trec_eval will dump ircl_prn. values, and you could
plug them in openoffice.
I prefer to use trec_eval as the results from the benchmark summary
often differ with trec_eval.
it would be gr

Hello,
I use Lucene 2.9.1 with two indices, which alternate each day. One is
live, the other is erased and renewed with the latest data.
The problem is that the index files will be deleted, but the file
handles are still available. If the program (JBOSS) is not restarted for
some time, the dis
Hi,
I am not sure if you are still searching the answer for your question. If
so, then please read on...
You can get the DF & IDF for each of the query terms in the query as below..
IndexReader reader = IndexReader.open(FSDirectory.open(new File(indexDir)),
true);
//Create a FilterInde
No answers but some things you could try:
There have been some reports of problems with file paths being
specified in different ways - UNC versus something else perhaps.
Use SimpleFSLockFactory rather than the default native class.
Try a recent version of lucene unless you already are.

I'd like to have all my queries and terms run through Unicode
Normalization prior to being executed/indexed. I've been using the
StandardAnalyzer with pretty good luck for the past few years, so I
think I'd like to write an analyzer that wraps that, and tacks a
custom TokenFilter onto the chain pr

It does sound like a good idea to not permit a null doc ID set, since
there is a convenient constant for the empty result anyway. :-)
And actually, it turns out tha
It would be helpful to know:
1) what version of Lucene you are using
2) what exactly like 167 of LibraryBuilder looks like (ie: what options
are you using when instantiating the IndexWRiter)
3) what filesystems are using on each of the two different machines you
are using.
4) does it really say
