I took a look at your changes, and I agree that they make things
clearer.  Thanks.

The text in "Lax Search" now says

  Search commands in Emacs by default perform character folding

But search-forward can be found using M-x apropos, and it is listed as
being a command.  So I think the text in the "Lax Search" node still
needs work.

Would something like the following be acceptable?

  The search commands that are described in "Incremental Search" and
  "Nonincremental Search" perform character folding by default, thus
  matching equivalent character sequences.

If that's no good, an alternative might be to say that "Some search
commands ... perform character folding", and to add a note along the
lines of

  To determine whether character folding applies to a particular search
  command, see the Help text for that command.
