Xapian discuss - Mar 2008 - how can i use stopwords?

Hi,

I do not understand the stopword function...

I've set the termgenerator like this:
$self->{'Stemmer'} = new Search::Xapian::Stem(german2);
$self->{'Stopper'} = new Search::Xapian::SimpleStopper();
$self->{'TermGenerator'} = new Search::Xapian::TermGenerator;
$self->{'TermGenerator'}->set_stemmer(
$self->{'Stemmer'} );
$self->{'TermGenerator'}->set_stopper(
$self->{'Stopper'} );

I've thought that xapian now exclude the stopwords automatic by the
stemming-language.

Could someone explain the stopword function?

Thanks.

Greetings

Sascha

No, it's still up to users to set the list of stopwords to use.

You need to call SimpleStopper->add() for each word you want to be in 
the stopword list.
