Text Box Variable and Wildcard

Does anyone know if there is a bug with using * as a wildcard in a Text box variable? When I use * as a wildcard in my text box variable it returns No Data. If I use * instead of the variable in my query I get results. Looking at the query inspector I see the queries are much different:

Query with * in the query, no variable:

AND * AND * AND * AND *"}}]}},

Query with * in the default value, text box variable used:

AND * AND * AND * AND \\*"}}]}},

what datasource is this query running against

Elasticsearch

Please post the full query with the variable being used

kubernetes.namespace_name.keyword: ${customer} AND ${pwiseLogAppender} AND ${custom} AND ${logtype} AND ${thread}
