It is explained in a section dedicated to "lax search", where other
kinds of non-literal matching are described.  I think that bringing
this stuff together in a single section makes it easier to describe,
as the features are similar with similar toggles.

This is the current implementation.  But a user manual should not be
driven by implementation, it should be driven by user-level POV, where
features can be similar even though their implementations are very

It doesn't get any prominent focus.  Please take a look at the manual:
this is described only _after_ we've covered incremental and
non-incremental search, word search, symbol search, and regexp
search.  It's actually quite close to the end of the chapter, just
before we describe replace commands.

This is not really relevant to documentation, which is the subject of
this bug report.
