Hi All,

I am using SolrCloud 4.10.1 and I have 3 shards with replication factor of
2 , i.e is 6 nodes altogether.

When I query the server1 out of 6 nodes in the cluster with the below query
, it works fine , but any other node in the cluster when queried with the
same query results in a *HTTP Status 500 - {msg=Illegal character in query
at index 181:*
error.

The character at index 181 is the boost character ^. I have see a Jira
SOLR-5971 <https://issues.apache.org/jira/browse/SOLR-5971> for a similar
issue , how can I overcome this issue.

The query I use is below. Thanks in Advance!

> My cluster contains 3 Solr instances. I have a collection consisting of one

> Without the facet.field attribute, it works fine on all the nodes.
> Is this some kind of double escaping when proxying the request?
