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 non-incremental 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 fancy
replacement command called query-replace which asks interactively
which occurrences to replace.

| • Non-Incremental Search: | Specify entire string and then search. | |
| • Word Search: | Search for sequence of words. | |

| • Regexps: | Syntax of regular expressions. | |
| • Search Case: | To ignore case while searching, or not. | |
| • Replace: | Search, and replace some or all matches. | |
| • Other Repeating Search: | Operating on all matches for some regexp. |
