title: "daily limit exceeded" when using Google custom search API
body: <p>I wanna crawl 200 results for about 2000 queries but it gives me a "daily limit exceeded" error. </p>
  
  <p>I want to confirm how many results can we crawl per day. Is there any solution that can solve this problem? Or the only way is to crawl a small part of queries each day...?</p>
  
  <p>My code to crawl google is as follow:</p>
  
  <pre><code>def crawl(query_list):
      http = httplib2.Http()
  
      # Construct the service object for the interacting with the CustomSearch API.
      service = discovery.build('customsearch', 'v1',  developerKey='my api key', http=http)
  
      res_list = []
      for query in query_list:
          json_res = service.cse().list(q = query, cx = 'my search engine id', num = 200,).execute()
          res_list.append(json_res)
  </code></pre>
  
  <p>Thank you!</p>
