I've been looking into this even more.
The weighting option seems to get left out. The more I try with
different options the more it seems they're not having an affect.
If I do a basic search:
Product.search(:conditions => {:title => "keyword"}) on an index that
I know has multiple records that have an exact match and a few that
have the keyword within the text I get a result set that orders the
records by ID.
This means that when I do this search:
Product.search(:conditions => {:title => "pancake"})
I get something like:
Title: Pancake
Location: Brisbane
Title: How to make a pancake
Location: Sydney
Title: Pancake
Location: Somewhere else
but surely the two records who's title is an exact match should come
first?
If I look in the development log I can see that the products are being
fetched by ID wit their ids in chronological order. This is then how
they are displayed in my result set. Shouldn't the ids being fetched
be ordered by relevance?
Am I correct of have I misunderstood?
Thanks
Shaun
