Greetings,
We're working on an application for a client that uses Solr (via the
acts_as_solr Rails plugin) to query a database of about 16 million
business listings. Part of our client's strategy is to weigh matches
on certain fields higher than others. We've been using Solr boosts to
accomplish this. However, what they want is for only the match with
the highest boost to figure into the relevancy. What we tried to do
was a query something like
(field_a:Food^40 OR field_b:Food^30 OR field_c:Food^20 OR
field_d:Food^10)
but from reading debugQuery output, assuming we search for "food", all
four fields are matching and boosting the relevancy appropriately.
What we need is a sort of short-circuiting OR operator; that is, once
it matches one of the fields (in this case, field_a) it will stop
evaluating everything else inside the parenthesized group and boost
only by that first field (in this case, only the boost of 40.)
From my reading of Solr and Lucene documentation, it doesn't appear
obvious that there's a way to do this. Has anyone ever tried to do
something like this? If so, how did you do it? Thanks in advance for
any help.
