Hi , I am using solr 4.7.2 verison.
I am using group.ngroups=true in my solr queries and recently shifted to distributed architeture of solr, where i add shards param in my solr queries as follow : http://localhost:8983/solr/foo/select?wt=json&rows=2&group=true&group.field=dcterms_source&group.ngroups=true&shards=localhost:8983/solr/foo,localhost:8983/solr/bar&hl=true But group.ngroups=true does not work well if i have documents of one group on all shards rather than on same shard. i have seen various jiras of solr, where it is written that issue is fixed in 4.9 version of solr. Would like to know , in 4.9 of solr , can we use same queries as earlier or i will have to change the queries to have facets instead of groups ? And also, if I have to upgrade to 4.9 version of solr, i would like to know the changes to be done to upgrade to 4.9 as well. Regards, Manisha
