Hey, I noticed commit 145503bbe4a5bf702cd13cb2e592111e8d7ca89a (Reimplement Database and WritableDatabase, 2017-10-05) added the phrase: "The terms are returned ascending string order (by byte value)" for termlist_begin. Is that also true for the 1.4 (or even 1.2) series? Also, is allterms_begin also the same w.r.t. ordering? Thanks.

Hi, While porting the unit tests from perl for the node binding I noticed a test failed. I basically create a document, add a few terms, add the document to a database and then call doc->termlist_begin().get_termfreq(). This throws "Can't get term frequency from a document termlist which is not associated with a database." What I think this means is that I can not call get_termfreq from a TermIterator obtained from a document (this is only available for a TermIterator obtained from...

Hello, Thanks James for the reply. That cleared a few things out. Apologies for replying late because of exams going on. I was going through the previous clustering API to understand how it worked and it seems like the the approach for construction of the termlists which are used for distance metrics use TF-IDF weighting with cosine similarity, which is very similar to the approach I would need

...ow positions of the terms that i want to display. But how to get the terms itself? Xapian::Document does not have something like GetTermByPosition(int position). Currently i am iterating through all of the terms, than through all of the positions, something like this: for (term = xapian_database.termlist_begin(docid); term != xapian_database.termlist_end(docid); term++) { for (pos = xapian_database.positionlist_begin(docid, *term); pos != xapian_database.positionlist_end(docid, *term); pos++) { if ( (*pos) == position_of_my_term)) my_term= *term;...

Hi, I'm using xapian with c# and mono and i'm having a segfault in get_weight. When i print the index variable, the value is clearly too high. I think something write over it. Do you have any idea on how i could trace the beginning of the segmentation fault ? Thanks, -- Yann
