Hi All,
We are upgrading from Solr/Lucene 4.5.1 to 4.10.4. When testing we found the
below issue.
The score field in the query response for a distributed query results in NaN.
This happens if the indexes were created in 4.5 and the query is received in
4.10.1.
Also the score in the explain statement with the debugQuery on is same with 4.5
or 4.10.
This issue does not happen for queries which involves single shard. Has anyone
faced this issue or know the cause/remedy of this behavior.
Thank you,
Rajeswari
Query is just Q=*:*&fl=score ,with the correct URL
