How to make use of default \_analyze in elastic search dsl python?

My query looks like below:

```auto
query = Q('regexp', field_name = "f04((?!z).)*")
search_obj = Search(using = conn, index = index_name, doc_type = type_name).query(query)
response = search_obj[0:count].execute()

```

Where do i put `analyze() method` so that i get to see how my `"f04((?!z).)*"` is getting broken into terms? Actually it seems like `'!'` doesn't work as regex. How do i change the anaylzer if default analyzer is unable to take `'!'` as regexp character?

I'm very new to use, finding little hard to accurately put analyze method in my code. PLease help.
