Searching and Replacement
*************************

   Like other editors, Emacs has commands for searching for occurrences
of a string.  The principal search command is unusual in that it is
"incremental"; it begins to search before you have finished typing the
search string.  There are also nonincremental search commands more like
those of other editors.

   Besides the usual `replace-string' command that finds all
occurrences of one string and replaces them with another, Emacs has a
fancy replacement command called `query-replace' which asks
interactively which occurrences to replace.
