Hello,
I want to search a wildcard string **on all fields of a document**. Is there any way to do it?
I was able to write this query but for some reason it always returns empty.
```auto
{"bool": {"must" : [{"wildcard": {"_all": "*search_string"}}]}}
```
Any help will be appreciated.

Hi @Sheharyar_Khalid
Reading the [answer](https://stackoverflow.com/a/34147611/18778181) says it's not possible because \_all is depreced.
Doc:
> `_all` may no longer be enabled for indices created in 6.0+, use a custom field and the mapping `copy_to` parameter
