What to #include, namespaces not obvious from the documentation

Describe the issue

For example, on this page I see uses of HasSubstring but nothing on that page tells me what namespace it comes from.

On this page I see

using ::testing::HasSubstr;

in examples, but #include <gtest/gtest.h> is insufficient to find that, and nothing on the page tells me what the right #include is.
