The bash man page refers to regex(3). On my BSD (Mac OS X) system, that refers to re_format(7), which documents the BRE and ERE regular expression formats. On an Ubuntu box, to choose a representative Linux example, that refers to regex(7), which contains the same explanation, and the GNU regex manual. This sort of "chained" man page reference is common. If you like info, `info regex' on a Linux box should display both pages.
