The full text of that part is as follows:

  The optional third argument NOERROR indicates how errors are handled
    when the search fails.  If it is nil or omitted, emit an error; if
    it is t, simply return nil and do nothing; if it is neither nil nor
    t, move to the limit of search and return nil.

Note the first sentence of the paragraph: this entire paragraph
describes how NOERROR affects the case when the search _fails_.  Thus,
the situation where the search succeeds is not relevant to the above
part of the doc string.

So I think this text is accurate and correct.

Fixed, thanks.
