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
more flexible replacement command called `query-replace', which asks
interactively which occurrences to replace.

Incremental Search
Search happens as you type the string.
Nonincremental Search

Search Case
