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.
