If I happen to subclass MultiFieldQueryParser unneccessarily (thought
need more than one default search but don't after all) would it have
any impact on performance ?
thanks Paul

Hi,
I'm new to Lucene. I'm indexed some documents with Lucene and need to sanitize
it to ensure
that they do not have any social security numbers (3-digits 2-digits 4-digits).
(How) Can I write a query (with the QueryParser) that searches for this pattern?
e.g. I can do [000 to 999] or [00 to 9
It is fixed now. I need to enable
qp.setAutoGeneratePhraseQueries(true);

Ganesh

Hello Damerian,
Please let me know, How you fixed the problem? I am facing similar kind of
issue.
My analyzer produces multiple tokens. When i search usig 3.0.3, the query
expands to +field: "token1 token2" but now in 3.5, +field(token1 token2). It is
doing OR search now. If either of the t

Please share your experience in 64 bit. How big your indexes are?

In the Javadoc page for the Similarity class, it says,
"Lucene combines Boolean model (BM) of Information Retrieval with Vector Space
Model (VSM) of Information Retrieval - documents "approved" by BM are scored by
VSM."

Phew, tricky.
The problem is purging is potentially costly... it iterates all
entries in the map (threads that have called get) looking for dead
threads.
Can you open an issue...? We can iterate there. Thanks for raising this,

HI Chris,
I didn't see your response. Thanks.
Actually I was recently playing in fooplot , an online plotting tool (one of
many), to examine the various formulas and getting a better handle on what they
do.
Thanks for the discussion of 'sweetspot'. I'm thinking this might help others
going

First of all thank you again for replying
You shouldn't use doc.removeField -- it's costly (the fields are a
list internally so we walk that list looking for which field(s) to
remove).
To reuse you can just use Field.setValue, and leave the Field instance
on the Document.
But: you should only do this if you really have a meaningful

Hello again!
First of all thank you again for replying my amateur questions.
I would like to rephrase my question because now what i described is not
the case and its not a problem of input methods.
I have made my custom analyzer which when indexing e.g the phrase "The
quick Brown Fox"
will p
I think many users of lucene use large memory because 32bit system's memory
is too limited(windows 1.5GB, Linux 2-3GB). the only noticable thing is *
Compressed* *oops* . some says it's useful, some not. you should give it a
try.
