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. The only catch with
this is that 'burger bar' will match 'Burger Bar', 'Bar Burger', and 'Just
Another Burger Bar'. Still, maybe that's good enough for what you need to do?
There's no special attribute for exact matches, I'm afraid, so you can't factor
it in to the custom sorting algorithm. And this is all theory - I've not tried
it myself, but I think it's worth a shot.
Cheers
