Advanced usage of Notepad++ find-in-files filter

Question

In the Notepad++ Find in Files dialog, there is a box for filter. Normally you would enter something like *.txt in there. Are there more advanced ways to use the filter?

Specifically, I am looking for the following functionality:

• Search all files except those of a specific extension
• Search multiple file extensions

Is this possible?

Answer 1

While I don't know how to search in all files except of a type, you can search in multiple file types by separating them with semicolons.

As in:

*.txt;*.lua;*.toc
