Thanks Yonik & Ken for both answers; I think the explanations went a
little over my head, but I think you understood what I was talking
about! Basically, a better filter to remove all possible accents (&
umlauts as a bonus, for completeness sake; I personally would have no
use for it).

Use TermDocs -

I think it is not possible, by only modifying Similarity, to make the total
score only count for documents boosts (which is the original request in
this discussion).
This is because a higher level scorer always sums the scores of "its"
sub-scorers - is this right...? if so there are probably two
Hi all,
There is an issue opened on Lucene:
http://issues.apache.org/jira/browse/LUCENE-665
that I'd like to draw your attention to and summarize here because
recently users have hit it.
The gist of the issue is: on Windows, you sometimes see intermittant
"Access Denied" errors in renaming
1) This is not java. Since it's not java, i can't even begin to guess
what odd excentricities might exist in whatever lucene port you are
using.
2) If this *were* java then it wouldn't work th way you want it to, since
you have the tf function returning "1" regardless of the frequency ..
I see. This is what I was curious about. Thanks!

Miles,
I understand you are trying to solve your problem by changing the index
contents (removing documents). Would it be possible to workaround it and
to achieve this during search, by only returning the relevant documents
and ignore the rests?
Just my 2 cents...

Hi,
I am using lucene from last few months...I have question about the range query
performance...
Is there any alternative of range query or can i fire a range query on a small
set of documents so that it can be less expensive...

Gracias por su atención.

This question surely shows how new I am to Lucene... but I'm interested
in removing terms from a lucene index. In particular, I'd like to be
able to delete all terms that appear in fewer than x documents (say
x=3). This is in efforts to reduce the feature set for some research
I'm doing.

It didn't really work for booleanqueries either. I thought it was working for
some hours but to my big disappointment I realized that this was not the case.
Im using two IndexReaders ( RAM and FS ) and one multireader. Creating one

I'm assuming that you're new to Lucene, so if you're an old pro you probably
already know all this
I think you'll have difficulty here. Lucene has no concept of lines, just
tokens and offsets. So here are a couple of suggestions off the top of my
head...
If the first line is the *only* way
I agree.
Thanks.
