[Xapian-discuss] MSet order

[Pierre-Alain Moellic]

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.
