Lucene Multiple conditions in Lucene query fetch wrong result

i am using grafana with elastisearch 5.3 . when i am using 2 or more conditions in Lucene query then result is incorrect.

Ex: Host_Name:"" and Disk_Id:" “
Host_Name:”" or Disk_Id:" "

None of these columns are in Metrics and group by. it works fine for me if i use one filter at a time in qurey.

Strange, works fine here:

I would open a support ticket/question in Elasticsearch forum, might be something wrong with your index?

working fine… issue was with extra white space.
