Yonik Seeley commented on SOLR-303: ----------------------------------- {quote}I'm not quite sure about GlobalCollectionStat. Is its purpose just to normalize weights from the shards?{quote} It's to make a distributed search score the same as it would if everything was in a single index. idf (inverse document frequency) is part of the scoring, so that component essentially does a distributed idf. I still use the PriorityQueue, but it's been modified since SolrJ returns objects rather than strings. I'll try to post a draft soon... if you understood the old code, it will be great for you to look at the new stuff to see what I'm missing. > Distributed Search over HTTP > ---------------------------- > > Key: SOLR-303 > URL: https://issues.apache.org/jira/browse/SOLR-303 > Project: Solr > Issue Type: New Feature > Components: search > Reporter: Sharad Agarwal > Assignee: Yonik Seeley > Attachments: fedsearch.patch, fedsearch.patch, fedsearch.patch, > fedsearch.patch, fedsearch.patch, fedsearch.patch, fedsearch.patch, > fedsearch.stu.patch, fedsearch.stu.patch > > > Searching over multiple shards and aggregating results. > Motivated by http://wiki.apache.org/solr/DistributedSearch -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
