Looking for a code or plugin with this function

When a user searches I want to display the keywords they searched for, each separately, in small rounded squares with an X to the right. When they click the X the search was repeated but without that keyword. When a new search is performed the keywords are added to the current keywords.

This type of search is common on many sites, so I thought it would be easy to find a plugin (free or paid) that does this but so far no luck.

Anyone know of something like this or has code I could use to add this functionality?
