 #### Pagination, $top, and $skip
 
 The default number of results returned is 100. You can override the default limit using the `$top` parameter. The higher the number specific for `$top`, the longer the API response will take, and pay attention to that different services does enforce a cap for number of records returned.
 
 You can paginate through multiple sets of results using `$skip`, this can help you process multiple records quickly. In addition, if you use `$select` to target only certain fields, the API response time will be faster.
