How to exclude certain filetypes from the search window?

[opal_1]

Let's say I'm searching inside a folder and I want to quickly exclude .jpg files from search result.
How do I do it quickly from the search window?

For example when I type .jpg at the end of the search it shows only jpg files. Is there any way to do that but in reverse?

Thanks

Please try the NOT operator: !

To find files NOT containing .jpg search for:

!.jpg
