Stemming and protwords configuration

[cs...@orange.com]

Hi,

We have a Solr server using stemming:

<filter class="solr.SnowballPorterFilterFactory" language="French" protected="protwords.txt" />

I would like to query the French words "frais" and "fraise" separately. I put the word "fraise" in protwords.txt file.

- When I query the word "fraise", no document indexed with the word "frais" are found.
- When I query the word "frais", I've got documents indexed with the word "fraise".

Is there a way to do not match "fraises" documents in the second situation ?

I hope this is clear. Thanks for your reply.

Christophe

Did you try putting them _all_ in protwords.txt? i.e.
frais, fraise, fraises?

Don't forget to re-index.

An alternative is to index in a second field that doesn't have the
stemmer and when you want exact matches, search against that
field.

Best
Erick
