The Search Bar on mobile is vertically oriented and very compact. You will find search bars when you want to add topics to watchlists or when you simply want to see stories for a single topic not on your watchlist. When you start to type, you will get a list of possible topics we have on our system.
We recommend that you choose one from the list, because similar names can be confusing and you might not get the exact information you are looking for. If you just add "Oil" (possible by choosing the "Keyword / Queries" item), you won't know if the content you receive is about Palm Oil or Heating Oil or companies with the name "oil" in them or funds with "oil" in their assets list. It is easy to see how quickly this can become confusing.
