Hey there,
Apologies for this not going out sooner -- apparently it was sitting
as a draft in my inbox. A few of you have pinged me, so thanks for
your vigilance.
It's time for another Hadoop/Lucene/Apache Stack meetup! We've had
great attendance in the past few months, let's keep it up! I'm alwa
I am continuing a work about wavelets in IR. In the bellow article you will

Hi Fabricio,
I will try to recap what you are trying to say...
you IR model does score documents that would not be returned by a
particular query. So you have some other indicator that make a
document relevant?! If it is not a term could you give use an example?
How would you decide if a doc is r

First, that a document is relevant to a query does not necessarily mean that
this document has to contain some query term. You can have other ways to
assert that a document is relevant to a query.

Hello all Lucene users,
I just wanted to let you in on the current release schedule for Lucene
2.9 (still subject to change):
Currently, we plan to go into official feature freeze tomorrow
(Wednesday, August 26 2009). That means we will try and keep the 2.9
code as stable as possible, only commit
Can you please elaborate more on the use case? Why if a certain document is
irrelevant to a certain query, you'd like to give it a score? Are you
perhaps talking about certain documents which should always appear in search
results, no matter what the query is? And instead of always showing them,

I already know about this, but I want to give a customized score for all
documents in collection, independent if wache document is or isn't relevant
to the vector model.
The similarity function is called only when the document is relevant to the
vector model.
Do you understand me?
Thanks!

Hi,
I have experience some strange things when dealing with Lucene queries.
I've read some threads on this list and realize that Lucene shouldn't be
seen as a complete boolean query language. However I try to understand
the Lucene-way and have one example that I wonder if someone can help me
Hi Simon,
10x for your answer.
Unfortunately the code that you suggest is compatible in speed with the
code that we use in our app (it was even a bit slower).
10x,
