Xapian discuss - Mar 2011 - MSet order

Hello

I defined a weighting scheme to simulate a king of "euclidean"
distance.
To test it, i used a database with 1000 documents.

If I run :
enquire.set_weighting_scheme(MyWeight());
Xapian::MSet matches = enquire.get_mset(0, 1000);
I have a correct list of results.

But if I run Xapian::MSet matches = enquire.get_mset(0, 10);
I don't have the top-10 results.
If I run Xapian::MSet matches = enquire.get_mset(0, 20);
I d'ont have the top-20 results and it's even not the same order than
the
previous top-10 (actually it's the top-10 with inserted results).

I'm lost !

Regards,

pa.

Did you implement the get_maxpart() and get_maxextra() methods
correctly?  It sounds like those are returning incorrect values, which
would cause optimisations to fire early, and would produce effects
such as those you describe.

If you're able to post the source code somewhere (eg, in a site like
pastebin.com), we might be able to spot the error.
