Pick the Lucene analyzer compatible with Brazilian Portuguese.
Such as the one at [1]. PyLucene, which Chandler uses for its full text 
search needs, comes with the BrazilianAnalyzer built in.
You may want to experiment with combining that analyzer with a 
LetterAnalyzer or the StandardFilter to see what best suits your needs.

I'm afraid not. The code should be changed to at least use a preference or 
base its analyzer choice on the current locale. In the meantime, If you 
change analyzers, to be complete, you also need to get chandler to reindex 
your data (changing the analyzer in the indexing code too, all in 
LuceneContainer.py in the chandlerdb egg). To get chandler to reindex your 
data, press the control key while Chandler is starting and pick the relevant 
option from the dialog. Or, from the command line, start Chandler with 
--reset-index.
