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.|
|• Searching and Case||Case-independent or case-significant searching.|
|• Regular Expressions||Describing classes of strings.|
|• Regexp Search||Searching for a match for a regexp.|
|• POSIX Regexps||Searching POSIX-style for the longest match.|
|• Match Data||Finding out which part of the text matched, after a string or regexp search.|
|• Search and Replace||Commands that loop, searching and replacing.|
|• Standard Regexps||Useful regexps for finding sentences, pages,...|
The ‘skip-chars…’ functions also perform a kind of searching. See Skipping Characters. To search for changes in character properties, see Property Search.
