Is it possible to match all but in letters order

[vsub]

For example I search for "t i o" and this will display a file named "part file one"
If all of those letters don't exist in the file name IN that order,don't display the file
For example "file part one"
As you can see all of the letters exist but they are not in that order

And also this may be the same\similar but it possible to find a file that contains all of the letters I am searching for
For example I don't know exactly how a file is named,but I do know what letters it contains

It can be named "part file one" or just "pfo"

Maybe regex(I am not good at using that)

[NotNull]

Maybe

*t*i*o*

? (with Match Path disabled)

(sounds like I am overlooking some complication?)

[vsub]

Hmm yes,this find what I was looking for,thanks
