Search query is saved as undefined if user searches from google.com

In app.js:

var query = window.location.search.substr(1).split("&")
var params = {}
query.forEach(function(q){
  var qs = q.split("=")
  params[qs[0]] = qs[1]
})

If the google search originates from the chrome search bar then:
windows.location="https://www.google.com/search?q=example+search&oq=example+search&aqs=chrome..69i57j69i60l4j69i61.2358j0j1&sourceid=chrome&ie=UTF-8" and //params.q => "example+search"
However if you search from the google homepage (www.google.com) you get the following:
windows.location="https://www.google.com/?gfe_rd=cr&ei=vAiIV9GnBKSA8QfI_afwAw&gws_rd=ssl#q=example+search" and //params.q => undefined so in that case the search query is not saved correctly; it is saved as undefined in the database.

Start in app.js at the query-string parsing shown in the issue and reproduce both Google URL forms. Verify that the search query is captured for the homepage URL as well as the search-bar URL, then confirm the saved value is no longer undefined.
