-----Original message----- > From:alessandro.benedetti <abenede...@apache.org> > Sent: Friday 27th January 2017 13:22 > To: solr-user@lucene.apache.org > Subject: Re: Distributed IDF in inter collections distributed queries > > I have an update on this, I have identified at least 2 bugs : > > 1) Real score / Debug score is not aligned > When we operate a shard request with purpose '16388' ( > GET_TOP_IDS,SET_TERM_STATS) we correctly pass the global collection stats > and we calculate the real score. > > When we operate a shard request with purpose '320' ( GET_FIELDS,GET_DEBUG ) > we don't pass the global collection stats so the debug score calculus and > rendering is not the same as the real score. > This can be really confusing and not easy to spot. > > Proposed solution : we pass the global stats for debugging as well > > 2) Using the ExactStatCache in a solo collection VS multi collection > scenario doesn't work really well with caching. > Specifically if we first execute the multi collection query, the global > stats cached will be the multi collections one, even if we then operate a > single collection query. > Vice versa applies. > > Proposed solution : the list of collections involved in the ExactStatsCache > should be affecting the hashing ( and consequent caching of the same global > stats) > > I think we should raise 2 separate bugs in the Solr Jira. > > What do you think ? > > > > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Distributed-IDF-in-inter-collections-distributed-queries-tp4317519p4317531.html > Sent from the Solr - User mailing list archive at Nabble.com. >
