Searching for documentation covering the regex characters Ansible uses

[Dave]

I'm trying to find a list of all regex characters Ansible uses in its definitions.

For example, the in the files module, the blockinfile definition has an insertafter parameter that accepts *regex* instead of 'EOF' but I don't see what type of regex is available or employed for word matching or substitution or how its defined.
