Tomás Fernández Löbbe commented on SOLR-8420:
---------------------------------------------
While looking at this patch I noticed that in the line 841 of
{{TestDistributedSearch}} it says:
{code:java}
rsp = query("q", "*:*", "rows", "0", "stats", "true",
{code}
but was intended to be
{code:java}
rsp = query("q", q, "rows", "0", "stats", "true",
{code}
We should fix that as part of this Jira too.
