hi, i am using lucene for the very first time and want to manipulate the
results, by adding some more factors to it, which file should i edit to
manipulate the search results
Thanks

Hi all,
I am using Hibernate Search (http://www.hibernate.org/410.html) which is a
wrapper around Lucene for performing search over info stored in the DB. I have
questions related to Lucene boosting Vs sorting:
Is index time boosting of documents and fields better than specifying sorting
para
Gotchya. Well, if you want to check a doc at a time you could use
getSpans for a NearSpan query and just count how many you get. No ideas
off the top of my head if you want the result like a score in that you
get it for each hit in a search of a whole corpus.

I actually hadn't implemented the TokenFilter solution before deciding not
to go with that solution, so didn't have any benchmark.
But eventually I have taken care of this problem with a different
variation of your quick and dirty solution. I have captured the character

I think you need to back up and think about what you're trying to
accomplish. Just throwing the file into a single document in
your index doesn't seem very useful.
Of course you can pre-process the input and index only what
you want. The examples in the Lucene demo just show
you how to index entir

Lucene, by default, only indexes the first 10,000 tokens and throws
the rest away. You can change this via IndexWriter.SetMaxFieldLength.
2G is a huge file. Are you indexing all that or are you indexing only
portions?

Hi Erick
Thanks. I found something interesting. I was indexing huge text files (>2GB)
and the search was not returning escape characters. However, when I moved
the line to a smaller file (20MB), it works fine. Is there a limit on file
size search by Lucene or would you know how do escape character
Karl,
I should have mentioned before, I have Lucene 1.9.1.

You can override the scoring system and only score by term frequency
(use a 1 or whatever creates a no-op for the other factors). If you have
indexed with norms than you will have to use a Reader that ignores them
to do this.

You can use it to examine the contents of your index

Have a look at the FunctionQuery capabilities in Lucene, whereby you
can use the value of a Field as a scoring factor. So, your
FunctionQuery would just do a simple calculation between the current
time and whatever date is in the document.

Hi,
Looking into older threads and some googling i came across some codes
where boosting is done at the time of indexing using time gap from 'epoch'
or a *base time*. With this approach what I am afraid of is that over a
period of time the boosting factor may go up and I may loose the relevence

Brain,
Can you simply describe the method you tried? I am very intertested in
that.

I would love to revisit this one. I implemented pseudo date boosting in an
overly simplistic manner in my app, which I know can be improved upon. Might
it be useful to reopen a thread on the topic?
