Description
The documentation says, RegexValidator matches the regex against the value, and hence ideally it must use regex.match but instead uses regex.search.
This looks like a bug.

So the [documentation](https://docs.djangoproject.com/en/dev/ref/validators/#django.core.validators.RegexValidator.regex) says, "regex pattern to search for provided value". I suppose this means, you try to see if value fits in the regex. But instead it sees if regex fits anywhere in the value. So in documentation, it must be "regex pattern to search for, in the provided value".

Where's the documentation you quoted? I see, "The regular expression pattern to search for the provided value". Presumably the documentation you mentioned should be fixed since changing behavior would be backwards incompatible.
