Hello,

We are migrating from solr 5.5 master slave to solr 8.0 cloud deployment.
for exactly same index and config, we are getting different results.

we also compared solr cloud (solr 8.0) and master slave (solr 8.0) with
same indexed data.

in all of above scenario we observed that different edismax queries are
being generated for same search term.

In our setup IDF and TF is set to 1 by overriding similarity class.
[<statsCache class="org.apache.solr.search.stats.ExactStatsCache"/> also
did not make any difference in our observation]

our main concern is, why edismax is generating different queries in master
slave and cloud even if solr version is same.

is there any way to generate same edismax queries in these three different
scenario (solr 5.5 master slave, solr 8.0 master slave and solr 8.0 cloud).


More info:

in cloud, we are using sharding based on one field F1.
we are fetching grouped results based on field F1.
ungrouped queries are returning different results.
