Searching and Matching

   GNU Emacs provides two ways to search through a buffer for specified
text: exact string searches and regular expression searches.  After a
regular expression search, you can identify the text matched by parts of
the regular expression by examining the "match data".

* String Search
Search for an exact match.
* Regular Expressions
Describing classes of strings.
* Regexp Search
Searching for a match for a regexp.
* Replacement
Internals of `query-replace'.
* Match Data
Finding out which part of the text matched various parts of a regexp, after regexp search.
* Standard Regexps
Useful regexps for finding sentences, pages,...
* Searching and Case
Case-independent or case-significant searching.
