Re: How can I check if a more complex query condition matched?
: I have a more complex query condition like this:
:
: (city:15 AND country:60)^4 OR city:15^2 OR country:60^2
:
: What I want to achive with this query is basically if a document has
: city = 15 AND country = 60 it is more important then another document
: which only has city = 15 OR country = 60
what you've got there will do that, but to a lesser degree so will a
simple query for both clausees...
q=(city:15 country:60)
will score documents higher if they match both clauses then if the only
match one becaues of the coord factor -- you can check the debuqQuery
score explanations to see the details. If you want the descrepencies in
scores to be more significant, you can go the route you have, or you can
customize the similarity to stricter about the coord factor, but that will
apply to all boolean queries.
: Furhtermore I want to show in my results view why a certain document
: matched, something like "matched city and country" or "matched city
: only" or "matched country only".
this is a bit trickier, but thanks to the new psuedo-fields feature it
will work in 4.0 (and already works on the trunk)...
any function can be specified in the "fl" param and each document returned
will include the value that document has for that function -- so
regardless of how complex or simple your main query is, you could use the
"query(...)" function in the fl to see what score it gets against some
other arbitrary function...
Here's an example URL using the example data/configs...
http://localhost:8983/solr/select?q=hard+drive&fl=score,id,name,is_canon:query%28{!v=%27manu_id_s:canon%27}%29

Re: How can I check if a more complex query condition matched?
There's no easy/efficient way that I know of to do this. Perhaps a good question is what value-add this is going to make for your app and is there a better way to convey this information. For instance, would highlighting convey "enough" information to your user? You're right that you don't want to enable debug in production, it can take quite a long time (see the timings when you DO enable debug). Could you consider some kind of one-off when a user really, really needs this info where you *do* add debugQuery=on but restrict the query to a single document they're interested in?

Re: How can I check if a more complex query condition matched?
Thanks for your reply, I thought about using the debug mode, too, but the information is not easy to parse and doesnt contain everything I want. Furthermore I dont want to enable debug mode in production. Is there anything else I could try?

Looks like you can extract these info from output of &debugQuery=on. http://wiki.apache.org/solr/CommonQueryParameters#debugQuery
