In Nautilus if I press CTRL+F I get a search box that helps me search in the current directory and sub directories for specific names, 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

All of this searches in the Nautilus search box I mentioned before. I ask this since the KDE's search is much better in this and gives pretty good freedom in searching for virtually anything, so I might not be learning how to use the Nautilus search option correctly.

Note that I am talking about the first search done since some of this options show AFTER a search is done so the user can narrow it down more by doing a more specific search inside the Search results (for the first search). I am asking here how to do any of the search options I mentioned above in the first search.
