Hi list,
we are using the kinda new JoinQuery feature in Solr 4.x Trunk and are
facing a problem (and also Solr 3.5. with the JoinQuery patch applied) ...
We have documents with a parent - child relationship where a parent can
have any number of childs, parents being identified by the field "parentid".
Now after a join (from the field "parentid" to "id") to get the parent
documents only (and to filter out the "variants"/childs of the parent
documents), the document score gets "lost" - all the returned documents
have a score of "1.0" - if we remove the join from the query, the scores
are fine again. Here is an example call:
http://localhost:8983/solr4/select?qt=dismax&q={!join%20from=parentid%20to=id}foo&fl=id,title,score
All the results now have a score of "1.0", which makes the order of
results pretty much random and the scoring therefore useless... :(
(the same applies for the "standard" query type, so it's not the dismax
parser)
I can't imagine this is "expected" behaviour...? Is there an easy way to
get the "right" scores for the joined documents (e.g. using the max.
score of the childs)? Can the scoring of "joined" documents be
configured somewhere / somehow?
Thanks a lot in advance,
best regards,
Stefan
