patch for retrieving attributes only

[Martin Sarsale]

Dear All, Pat:

For a specific query we had on our system, we could build the answer
with just the Sphinx index attributes values which we found it's very
fast compared with going to the db server to retrieve the real data.

So we patched TS and added a search's :attributes_only implemented in
a similar way to search's :ids_only.

Pat: are you interested in this patch? it's just a few lines, (we
hope) harmless and I think it adds an interesting capability to TS:

if options[:ids_only]
replace @results[:matches].collect { |match|
match[:attributes]["sphinx_internal_id"]
}
elsif options[:attrs_only]
replace @results[:matches].collect { |match|
match[:attributes]
}

Thanks in advance!

Hi Martin

Thanks for the patch - I'd probably shy away from pulling it into TS proper... however, if you wanted to write a patch that just returned the raw Riddle results (:raw => true), and then you have a helper method that pulls the attributes from that in your own code. This would keep it as something a bit more useful to more people.

Still, if others start requesting that they just want attributes, then maybe this is worth pulling in.

Thanks
