Lemmatisation search in Solr

Hi,

I am implementing Lemmatisation in Solr, which means if user looks for
"Mouse" then it should display results of Mouse and Mice both. I understand
that this is something context search. I think of using synonym for this but
then synonyms.txt will be having so many records and this will keep on
adding.

Please suggest how I can implement it in some other way.

Thanks,
Amit Garg

stemming and synonyms are working fine in the application but these are
working individually. I guess I will need to add the values in synomyms.txt
to achieve it. Am I right?

Actually its the project requirement to implement the lemmatisation. I also
looked out for lemmatisation but couldnt get any.

Thanks,
Amit

Have you looked for any open source lemmatizers?  I didn't find any in  
a quick search, but there probably are some out there.

Also, is there a particular reason you are after lemmatization instead  
of stemming?  Maybe a "light" stemmer plus synonyms might suffice?
