Hi all,
I am new to Lucene project, would like to get some information
1) Can we use Lucene project as a search engine for code repository
2) If yes, how should the code component cataloging should be done so as to
have effective and quick search.

: The two symptoms of this not behaving as expected are
: 1) ir.docFreq(t) does not always equal the value returned by
: ir.termDocs(t).read(docs, freqs) (see below for actual syntax used).
: 2) Even after optimizing, I still have the same dupes in my index.
As far as #1, i don't know much about
I noticed in my lucene index that I had mistakenly indexed some documents
multiple times. I wrote the following piece of code to find and eliminate
the duplicates, but it did not behave as expected.
Background:
Every document has an ItemId field that was indexed as a keyword. Two or
more documents
here you can play with boost
(+includes:(red frogs) -excludes:(red frogs))^2.0 excludes:(red frogs)^0.5
you can also play with numbers to achieve best results.
this is first solution I've thought about(I mean there may be more efficient
solutions)

That works very well - thank you for your quick reply. As a followup
question, what if the desired effect was to force hits containing terms in
the 'excludes' field to appear below other hits?
Example using the same setup as before:
Query: red frogs
Result: both documents would be returned, b
string query should look like: "+includes:(red frogs) -excludes:(red frogs)"
You can play with MultiFieldQueryParser a bit.

Here is the logical structure of the document I'm working with:
The 'Document' has two fields:
'includes' - List of terms that provide positive boost
'excludes' - List of terms that provide negative boost
Here is a usage scenario:

There is a bit of it demonstrated in Lucene in Action. Here are some

Hi,
Can someone please explain me how do I use the CachingWrapperFilter?
I see that it's built in a decorator way (getting on the constructor another
filter and decorate it with caching), still I don't see any basic filter to
be the 'root'.
On the tests I saw there is a MockFilter, but I couldn
