Using relevance when sorting by generated key
Hi all, I am trying to implement a scheme where documents in an MSet will be sorted based on relevance as well as geographical distance from a given (non-fixed) point. I understand that this can be accomplished by using PostingSource in order to implement a custom weighting scheme that would combine BM25 weighting and distance. The problem is that I am using perl and PostingSource is not

I've set everything up and then I tried following on an instance of Xapian::Enquire: : enquire = Xapian::Enquire.new(database) enquire.query = options[:query] : sorter = Xapian::MultiValueSorter.new sorter.add(0, true) sorter.add(1,

Changing adapters in ActiveRecord does not change the generated sql
If I establish a new connection with a new adapter (ie. switch from mysql to postgresl) the generated sql is still mysql specific. I tried all sorts of reset methods on AR::Base but to no avail.

Capturing the sql from a statement without executing it?
Hi guys, Is there an elegant way to capture the sql that would have been executed by an ActiveRecord statement, without actually executing it? :) I''m imagining something like sql = User.find(1).groups.to_sql or perhaps sql = ActiveRecord::Base.capture_sql { User.find(1).groups } resulting in sql = ''SELECT * FROM groups INNER JOIN memberships....
