Normal search

You can search text as in most programs using the Find/Replace dialog. You can open this dialog by selecting Search->Find (or pressing

), Search->Replace (or pressing

) or Search->Find in Files. Each of these options will open the corresponding tab in the Find/Replace dialog. This dialog will always stay on top of the text, but you can still keep on editing the text if it's opened, and you can set it to be transparent (using the Transparency option) when its inactive (On lose focus) or at all times (Always). The slider controls the amount of transparency. Note that transparency is only available on Windows 2000 and later.
In the Find what field, type the text you want to find. This is automatically filled with the current selected text when the Find dialog is opened. The drop down list contains previous search items if a search was performed before. See also Search Mode.
The section below the Find what field allows you to mark and indicate all hits for a certain search. Mark Line adds a bookmark (see Bookmarks) to the line with a hit, Style found token will give the matching text a different color (configure with the Styler Configurator) and Purge for each search will clear all bookmarks and highlights before searching again.
To perform this, click the Find All button in the section. To clear all the results, click the Clear button.
The In selection button will only search inside the selection.

Match whole word will only result in a hit if the match consists of an entire word, not if its partial (for example (but not limited to), whitespace separated).
Match case enforces that hits have exactly the same case as the query. If this is disabled, the search is case insensitive.
Wrap around will start at the top of the file when the end of the file is reached when searching, depending on the location of the cursor.

The search mode determines how the query will be handled.

In Normal, the text will be searched literally.

In Extended, special character sequences will be interpreted as special characters such as newline characters. In this case, you can choose from:

\\ - Backslash character;
\t ΓÇô TAB character;
\r ΓÇô CR character;
\n ΓÇô LF character;
\0 ΓÇô NULL character;
\x## - Hexadecimal value (between 00 and FF);
\d### - Decimal value (between 000 and 255);
\o### - Octal value (between 000 and 377);
\b######## - Binary value (between 00000000 and 11111111).

In Regular Expression, the query will be handled like a regular expression. Because Notepad++ makes use of the Scintilla regex engine, it is the same as with SciTE, so a full list of regex options can be found here (with the difference that POSIX mode is always on, this is not an option):

with some examples here:

The search direction determines to what relative direction of the cursor will be searched. Up means text before the cursor will be searched, Down means text beyond the cursor will be searched.

To find the (next) hit, press Find Next (or Enter). Count will count the amount of hits the search will result in. Find all in all opened documents will search all opened documents and displays a list of results for each file, see also Find in Files.

Close simple closes the search dialog (close button and ESC do the same).
