Pat - Wouldn't that be equivalent to giving the "name" field a higher weight?
I think that at this point, the best way for us to get exact name matches back first will be to use the phrase searching, and do two searches, one for a phrase, and one regular. But I will argue against the overhead this would cause, so I guess we're just going to punt on this requirement. :) Thanks for your help and thoughts on this. -Steve On Jan 5, 12:40 am, Pat Allan <[email protected]> wrote: > Hi Steve > > You may want to look at having a second index, with just the name in it, and > then you should be able to rank that index a bit higher. > > define_index 'business_name' do > indexes name > end > > And then for searching: > > Business.search 'burger bar', :index_weights => {'business_name_core' => 10} > > Any indexes not mentioned have a default weighting of 1.
