The mechanism to which you are referring is called “Token Input” and there are quite an array of JavaScript solutions. Here are two jQuery solutions to get you started:

jQuery Tokeninput
A jQuery Tokenizing Autocomplete Text Entry

Tokenfield for Bootstrap
Advanced tagging/tokenizing plugin for jQuery and Twitter Bootstrap with a focus on keyboard and copy-paste support.

Keep in mind that Token Inputs require some sort of dataset from which to pull results. If your goal is to use this for a keyword search it may be a bit too niche.
