More details may change my opinion (not quite sure how others feel
yet), but with the way you've described it so far, it seems like all
you need is a basic string matcher:
For every message:
- if <blah>message.subject<blah> is found in the pool, then this
message is "similar to" the message in the pool
- if no such message could be found, then this message add it to the
pool and wait to find more like it
Please describe the problem in greater detail if this seems too
simplistic.

Well, the similar definition that I'm looking for is the number
2, maybe the number 3, but to start the number 2 is enough. If you
guys think that is not a Lucene problem what else tool can I use to
implement this requirement??
Thanks

I don't know how much of this is a Lucene problem, but -- as I'm
sure you will inevitably hear from others on the list -- it
depends on what your definition of "similar" is.
By similar, do you mean:
1. Identical, except for variations in case (upper/lower)
2. Allow 1., but also allow prefixes/suffixes (e.g., "FW: " or
"... (summary")
3. Allow 1., 2. and permit some new terms ... how many?
4. Allow all of the above and allow some changes to terms using
stemming (E.g., "Google releases Chrome" is similar to "Google
announces the release of its new Chrome web browser")
....
I'm sure you see where this is going. So ... how do you define
similar?
Good luck!

Hey all,
I want to know how much two Strings are similar! The thing
is: I'm processing an email box and I want to group all messages
that have the subject similar, makes sense?? I looked on the
documentation but I didn't find how to accomplish this. It's not
necessary add the messages or the subjects on some kind of index.
I'm using 2.3.2 version of Lucene.
Anyone has some idea?
Thanks in advance.
