FIXMEs in Search::Xapian
Carrying on this conversation: http://lists.tartarus.org/pipermail/xapian-discuss/2007-March/003513.html void TermGenerator::set_stopper(stopper) Stopper * stopper CODE: // FIXME: no corresponding SvREFCNT_dec(), but a leak seems better than // a SEGV! SvREFCNT_inc(ST(1)); THIS->set_stopper(stopper); It would be good to fix these FIXMEs. A class-level HASH could be maintained of contained objects. Any...

how can i use stopwords?
...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

Problem with stop words by indexing
...e but it does not work at all. I have my writableDatabase and my termGenerator (indexer) and they work well both together: I can index texts and search trough the database correctly. But if I add (before indexing my texts): Xapian::SimpleStopper stopper; stopper.add("testword"); indexer.set_stopper(&stopper); ... the result is exactly the same as before. I have checked with delve and "testword" is indexed. Do I use the SimpleStopper in a right way? Regards Emmanuel

Proper noun stemming
Hi All I was wondering if anyone had a solution for the following problem. I user QueryParser to stem my documents before adding them to a database. During the stemming process I would like to find a way of keeping proper nouns that span two or more words together as a phrase. For example "New York" or "Gordon Brown" or "Prime Minister" get spilt up. I see
