Range query on multiple fileds with pattern matching

I want to execute a range query on multi fields with a pattern like:

GET /testindex/testtype/_search
   "query": {
      "range": {
         "a*": {
            "gt": 14

I set a* in range query field name to do this query on all fields that start with 'a'. how can I do that?

I do not think this is supported.
