title: How to integrate keyword search function with web browser on iOS?
body: <p>There is a custom web browser in our app. We want to show keyword suggestions when user input some words in search field. Is there some Google api for this?</p>
  
  <p>I've found the similar api of Baidu:</p>
  
  <p><a href="https://m.baidu.com/su?&amp;from=wise_web&amp;action=opensearch&amp;ie=utf-8&amp;wd=keyword" rel="nofollow noreferrer">https://m.baidu.com/su?&amp;from=wise_web&amp;action=opensearch&amp;ie=utf-8&amp;wd=keyword</a>.
  This api will return a response in json format.</p>
  
  <p>How about Bing and Yahoo? Do they have some kind of keyword suggestion api?</p>
  
  <p>Thanks a lot!</p>
