Also, please note that I thought about it and realized that I mispoke
when I sent out my original suggestion. You don't want an untokenized
field in your case, you want an unstemmed one instead.
This will allow you to get the functionality you are looking for.. at
least I believe so ^^
Anyhow, best of luck!

Thanks for the reply.
I will try to add an other data field.
I thought about this solution but i was not very sure. I thought that was an
easier solution to do that...
best regards

You could also add another data field to the index, with an untokenized
version of your data, and then use a multifield query to go against both the
stemmed and exact match parts of your search at the same time.
This is a technique I've used quite often on my project with various
different requirements for the second field. Mind you it makes the indexes
bigger, but unless your dataset is large its not really a huge problem.

The way I've solved this is to index the stemmed *and* a special
token at the same position (see Synonym Analyzer). The From your
example, say you're indexing progresser. You'd go ahead and index the
stemmed version , "progress", AND you'd also index "progresser$"
at the same offset. Now, when you want exact matches, search for
the token with the $ at the end.
This does make your index a bit larger, but not as much as you'd expect.

Hello,
I have a stemmed index, but i want to search the exact form of a word.
I use French Analyzer, so for instance "progression", "progresser" are
indexed with the linguistic root "progress".
But if I want to search the word "progress" (and only this word), I have
to
many hits (because of "progression", "progresser"...)
The field is indexed, tokenized and no store...
Is there a way to do this, I mean to search an exact word in a stemmed
index
?
I suppose that I have to use the same analyzer for indexing and
searching.
I try with a PhraseQuery, with quotes...
Ps : I use lucene 1.9.1
Thanks
