title: Input search bar from an array of keywords
body: <p>For my app, in nodeJS, I want to create a keyword selector, similar to the tags one in the Ask section of StackOverflow.
  I know how to retrive an array of key words and pass it to the ejs section, but I'm clueless of how to proceed with the keyword searchbar</p>
  <p>What I pictured, is that when an user is typing the first letters of the keyword, the matching ones start appairing in a section below, and the further the user types, the smaller the selection.</p>
