Explorer plugin - ability to search for just files, folders, apps, etc.

To be able to search for whatever *general type* of thing you want would be nice. And be able to change the action keyword(s) inside the Explorer plugin to suit ones preferences. Like say, `f:` for files, `fol:` for folders or maybe `app:` for apps, etc. Maybe the ability to help define those parameters. For instance, adding or removing different file name extensions to be looked for when searching for just files or just apps. Just some thoughts I've had. Thanks for your consideration.
