try a testcase as follows: #-------------------tester.py------------------from PyLucene

def tokenStream(self, fieldName, reader): class charTokenizer(object): def
isTokenChar(self, c):

print 'Merci' for each in strs: print each.termText(),
each.type()#------------------------------------------------------------- Simple as it is,
however, it roughly didn't work out.Message:TrackBack:File 'tester.py', line 21, in

It works fine for me. Please provide more information. What are version are
you running ? What operating system ? etc...
