Feature: Implement search bar with suggestions capability

[DuarteMCSilva]

• Search bar instead of search dropdowns.
• Include a suitable debounce time

An example of component implementation:

const source = fromEvent(input, 'input');

source.pipe(
  debounceTime(300),
  map(event => (event.target as HTMLInputElement).value),
  switchMap(query => makeSearchRequest(query))
).subscribe(results => console.log(results));
