+1, with the same assumption ("when you say...").

However:

* it should be "the search words, disregarding punctuation" (comma - it is not
the words themselves that disregard punctuation)

* "ignoring" is better than "disregarding" here

  And just what do we mean by the computation of REGEXP paying no
  attention to punctuation?  Maybe an "(e.g. ...)" is in order.

* "searched for a literal string" (or "searched for a regular string") is
perhaps better than "searched for a string"

  FWIW, the doc string for `isearch-forward-regexp' refers to a
  literal search as "a regular string search".  But I'm not sure
  that "regular string" is a good choice in such contexts, as it
  can suggest having something to do with regular expressions.
