I've been trying to boost fields using MoreLikeThis, I haven't been able to cause the order of the products or their score to change by changing the field boosts.
I've tried using mlt.ql=field1,field2&mlt.qf=field1^2+field2^1 and several other configurations of the url to try and boost fields, it doesn't seem to make a difference, any idea how I can boost a field this way? Eva
