I have Grafana v.5.2 that uses Elasticsearch 5.5 as datasource. I am trying to use a wildcard search as specified in Lucene documentation. Yet I seem to get strange results.
If you look at this screenshot you’ll see that I am searching for a document wild a field named sender that starts with a substring equal to “AC”, yet none of the returned documents have a sender that starts with “AC”.
Have I missed or misunderstood something?
