I have a panel querying an Elasticsearch data source. I have two queries which use the exists query to determine which field to GroupBy. For example, the queries are:
VOName:$vo AND ResourceType:$type AND exists:OIM_Facility
VOName:$vo AND ResourceType:$type AND NOT exists:OIM_Facility
When I display this in a table, I want to merge the OIM_Facility and OIM_Site columns. In a previous version of Grafana (4.6.3), they would merge automatically.
