Yes lucene by default would only tackle exact term matches unless you use a

Hi Ian,
I guess that could be achieved if you write code to read the queries and
query for each document (using lucene).
Assuming that I got the question right! :)

Hi Rajiv,
If 'm interpreting your problem correctly, I'd suggest you to try using a
phraseQuery with an appropriate slop value. Though again it depends on what
is it that you exactly are trying to fetch.

slop value (using ~) in that case while forming the
query, also you could form an 'all words' query i.e. Boolean 'AND' or (MUST
clause in case of lucene). so that your search results include all documents
containing ALL the searched tokens.
Hope this clears it up!

Hi msr,
Perhaps this could be useful for you. Lucene implements a modified vector
space model in short.

Its about building a custom similarity class that scores using your

This might help in that case,

Hi Paul,
Lucene is a 'text only' saerch lib. i.e. as long as you feed in anything as
a string, you'd be able to use lucene else I don't think there's a way.
How do you even intend to search in those binary files? as in... what would
be the keyword/phrase? asking out of cu
other).
As per my knowledge lucene should be a better solution that anything else
that 'I know of' for such a thing, but there'd be a few things that you
would have to build yourself as well.

You could then open your reader in the regular fashion straight off the RAM
based tmpfs.
You could also go through the archives for suggestions.

Hi,
Actually I'd really suggest you to 'buy' a copy of Lucene In Action - 2nd
Edition. Its currently available as MEAP and its amazing. Perhaps the prices
are also down 40% or something, though 'm not really sure about it.
