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 examine the "match data" to
determine which text matched the whole regular expression or various
portions of it.

String Search

Search for an exact match.

Regular Expressions

Describing classes of strings.

Regexp Search

Searching for a match for a regexp.

POSIX Regexps

Searching POSIX-style for the longest match.

Search and Replace

Internals of `query-replace'.

Match Data

Finding out which part of the text matched

various parts of a regexp, after regexp search.

Searching and Case

Case-independent or case-significant searching.

Standard Regexps

Useful regexps for finding sentences, pages,...

   The `skip-chars...' functions also perform a kind of searching.

Note: Skipping Characters.
