Try the Snowball Porter filter factory. The algorithm is specified in plain text files, so adding new stemmers to the codebase is pretty easy. The hard part is finding a good specification of the algorithm for Brazilian Portuguese. A Google search reveals some references to Brazilian Portuguese versions of the Porter algorithm. Maybe one of these is suitably unencumbered for implementation and distribution as free software. As a last resort, there already is a Snowball Porter stemmer for Portuguese in the SOLR codebase. However, I do not know how suitable it would be for adaptation to Brazilian Portuguese, as I know zilch about the variant spoken in Portugal. Best regards - Christian
