If you want to modify the way Lucene scores documents, I guess you need to
extend Similarity class and provide your own implementation. Take a look at:

Hi Marquin,
So you have a field that you want to sort on, well thats pretty much a
straight task in lucene.
Sort sort = new Sort();
sort.setSort(, true/false);

Hello,
Im using Lucene 2.4.1 and Im trying to use a custom HitCollector to collect
only the first N hits (not the best hits) for performance. I saw another
e-mail in this group where they mentioned writing a HitCollector which throws
an exception after N hits to do this. So I tried this approa
Hello everyone. New here to Lucene, amazing product, but takes some time to
wrap my head around it all heh.
So I have a basic question regarding indices. I have a "document" with
various fields (content, post date, last viewed). The majority of these
fields are quite constant, but clearly the
Only the results from the query should be sorted. The field
caches do get loaded for all values of a field though, is that
what you're seeing?

Hi Jason,
Thanks for the advice.
However I was just working through the example. I actually don't want to
search on numbers / dates / geo etc and was looking at custom sorting.
It appears that custom sorting, or even sorting for that matter is not
useful if every document will have sorting app
Hey Jim:
I'm not sure if Standard Analyzer would do this for any such character,
unless you qualified the pre-pended string and a period so it fits Standard
Analyzer's definition for HOST.
However, if you want, you could add a Filter that you use after the Standard
Analyzer's Filters are done tha
Hi,
This is a kind of followup to a thread a couple of weeks ago.
In my indexer, I want to pre-pend a string to certain terms to make it easier
to search. So for example, if I have a string "XXX", I want to add, say,
"field1" to it, to get "field1XXX" before I index it.
To make it easier to s
Generally you should add javadoc, add/extend/modify test and eventually run
all test (they should pass ;) . Once you are there you can upload a patch
and add all necessary infos to the issue.
If you are not a committer you can not assign the issue to yourself afaik.
Make sure you meet compat polici

How to give a customize score for all documents independent of the vector
model?
I already know how to give a customize score, but I want to give this
customize score for all documents in the collection, regardless of what is
relevant to the vector model.
How to do this?
Now, thanks!

Hi,
I'm currently looking at sorting in lucene, and to get started I took a look
at the distance sorting example from the Lucene in Action book.
Working through the test DistanceSortingTest, I've noticed that performing
the SORT ends up sorting the whole index!
To test this I did the following:

Valery,
FWIW, to answer this question, I think the answer is still "it depends".
I agree with John, I think it is much easier for your tokenizer to
create tokens that contain all the context you need for the downstream
filters to do their job.
I don't think you can put some exact specification on

right, it wouldn't be a good separation of concerns.
That's why I wanted to know what you consider as "Tokenizer's job".

That code looks fine...
What OS/filesystem are you using?
Can you make a small test case that shows the issue?

Nope, never heard of him! But with a great name like that I'm sure he'll

Hi Valery,
I'm inclined to disagree with the idea that a token should not be split
again downstream. I think that is actually a much easier way to handle
it. I would have the tokenizer return the longest match, and then split
it in a token filter. In fact I have dones this before and it has wo
24 matches
