In Nautilus if I press CTRL+F inside a folder I get a search box that helps me search in the current directory and sub directories for specific names and types of files, but what if I want to:

• Find ALL files (including files without extensions)


• Find a file without an extension (Without the dot symbol or without any other name/extension separator)


• Find a file with/without a special character


• Find all files that start/not start with a character


• Find all files that end/not end with a character


• Find all files that start/no start with a character but end/not end with a character


• Find only files/folders


• Find files with specific text in them


• Find files with less/more/equal than/to X size


• Find files modified/created in X date

I ask since the KDE's search has all of this ways of searching for especific types of files and is much better in thism giving a pretty good freedom for when I want to go searching for virtually anything.
