Loading spinner things in SearchResults.js

• Placeholder for while results are being fetched:
  • New state value - searching, setSearching = initially set to true
  • if the state is equal to true, return "Searching..." and nothing else- possible loading spinner later
  • When the results are fetched, set searching to false
  • When false, we display the normal page with the results

Not sure:

1. in what component / file this logic needs to be present
2. you mention state is null, which state exactly?
