[Xapian-devel] weight scheme with document values

[Eric Langevin]

Hi guys,
   I resently used  xapian to sort some documents by distance between 2 
points.
I implemented a MatchDecider which work well.

I now tried to implement a Weight scheme to put my document in ascending 
order depending on the distance...
My information to calcul distance is in values in the document.

How I can access document values from Weight to be able to add some 
sum_extra weight ??

I just tried to create a function in Weight that look like:
Xapian::weight get_sumextra(std::map<Xapian::valueno, std::string> 
values) const;
to calculate an extra weight from my documents values...

But now I going deeper and deeper in the code to make this functions 
working...
Is it the good way to do this or there is an easier way ??

Thanks a lot

Regards.

Eric
