This is an excellent question.
You are right, what we really need is efficient reopening of an
IndexSearcher. Creating & warming a new IndexSearcher can be
expensive due [at least] to populating the FieldCache.
This has been discussed before, eg here:

Hi all,
I am using StandardAnalyzer() to index the data. I am getting false
hits in ~ operator query.
Actual data is: "signals by magnets of different strength"
and when I am parsing a query: "signals strength"~2 , I am getting a
hit which is a false result.
I am using QueryParser.
Please

I'm developing an application using lucene which will evaluate the
representativeness of a list of keywords within a collection of documents.
I'm doing this by indexing the documents and then, loading the list of
keywords and using the IndexReader Class and DefaultSimilarity, retrieving

For one, this loop calls next() twice in each iteration,
so every second is skipped... ?

Okay, now i feel real stupid :p
Seen as that solved all my problems (i think),
thank you very much,

Glad it helped! (btw it's always like this with,
debugging - others see stuff in my code that I don't)

Hello,
I'm building a ticketing system for my company and am using Lucene for some of
the more complicated queries. I'd say my application differs from the typical
lucene application in that my documents are (re)-indexed more frequently, the
query load is actually relatively light, and most of
Looks like you are using FieldCacheImpl to count search results for
each category. ( or called facet search by a fancy name ).
Well, it's a cache and the terms are loaded in the memory.

Those terms could be coming from a lot of diff. places.
What size JVM heap, etc. are you giving your application? My guess is
your index is too big to fit into RAM, you probably need to use a
FSDirectory or give it more RAM, but it is hard to say for sure w/o

Interesting... I didn't explicitly turn that on... I'm creating a query using

algorithmically somehow invoke the FieldCacheImpl? If so, anyway I can turn it

Thanks for the reply. The backup of the index on disc is around 80 MB. I'm

I am wrong about the facet search. You are using Sorting, which also
use FieldCacheImpl.
Doesn't seem a way to turn it off though.

It's hard to debug just by your description. But I think in general,
you should close the reader and searcher, after you update the index.
BTW: If you are using database, my software DBSight does this kind of
pruning out old data and keep the index up-to-date. No memory leaks
etc. It's not related
Isn't MultiPhraseQuery what is desired here? you can add Term[]s per
position and at least one term in each array must much.
