Query_string containing the "/" character

[ffknob (Flávio Knob)]

Hello,
does anyone know why I'm getting the following error when trying to search for a string that contains the "/" character? It is not listed in the Lucene special characters (and even trying to escape it doesn't help).
Thank you

Search:

"query": {
  "query_string": {
    "query": "2593-0200/92-1",

Error:

Ok, but it is a reerved character for Elasticsearch

I changed my query to "query": "982\\-0200\\/11\\-9" but it now it fails with:

      "caused_by": {
        "type": "number_format_exception",
        "reason": "For input string: \"982-0200/11-9\""
      }

A couple of things ...

1. it worked for query string 2593-0200/92-1 by double escaping ... 2593-0200\\/92-1.
2. Can you use text query via match etc instead of query_string? It worked for me even without escaping.
