Krusader is convenient for disk search by file names and their content, but it is slow for code search as it  traverse all subfolders in search point, but as developer I whould rather skip binaries folder "bin", "target", ".git", ".svn"..... . 
Now it is possible to spesify full path to ignored folder, and useful when you do search from "/", but it does not make sense for small folders espesially then we have al ot of them.

So please extend "Don't search in" to allow regexp strings to be provided here, or any other way ...
