One text field with two searchable values [MOVED]

Hello. Is it possible to create one text field “Favorite music bands” with few searchable (clickable) separate items?

For example user set with comma: “Nirvana, Metallica, Quinn” and system will display it as 3 searchable items?

I've seen this feature in some social network.

Or it’s not possible and I need to move topic as feature request?

Thanks.
