Hi,  
I'm new to elasticsearch. I would write a query, that matches a document with the following attribute:

`description: 20*40x555`

I want the query matches with the following inputs:

- `20X40X555`
- `20*40*555`
- `20x40x555`
- the combination of these

I tired the wildcard, and the regex query also. If the document's attribute does not contains any asterix characters the query works fine, but when the description attribute contains an `*` character it does not find.

I tried with the following queries:

with wildcard:

```auto
{
  "query": {
    "bool": {
      "must": [
        {
          "wildcard": {
            "short_description": "*20?40?555*"
          }
        }
      ]
    }
  }
}

```

with regexp:

```auto
{
  "query": {
    "bool": {
      "must": [
        {
          "regexp": {
            "short_description": ".*20.*40.*555.*"
          }
        }
      ]
    }
  }
}

```

When the short attribute is ex `20x40x555` both of these working, but if I change the value to `20*40x555` it does not returns the document unfortunately.

How can I achieve to get results when the value of the sort\_description is eg. `20*40x555` ? Thanks!

What's the mapping of your field? If it's `text` try searching the same content against a `keyword` field. If you've used default mappings you may have `short_description.keyword` already mapped.
