Proposal
I propose to add a new set of find functions for basic_string and basic_string_view, which take and return iterators instead of indices. These functions will have the same name as the existing ones, but with an “i” prefix. For example:

To me, an "i" prefix suggests case insensitive search. Boost, for example, has "icontains" and "ifind_first" that are case insensitive. Perhaps consider a different name.
