`!` works with only character range or a single character.

I have a string say, abchello. I would like to match something bcdhello. i could write something like this !a!b!chello. Now if i write this , it doesnot match hbhhello. Which i feel is according to the docs. But my use case requires to use it over a substring or string. Not just the character match. could this be supported or it can be already done?
