As mentioned in [node:10644] and [node:10734], we’re still doing some work on the metadata in 1.1 search responses. “Classic” pagination won’t be available in this method, and you should use the same methods suggested in [node:6213] to navigate search results.
refresh_url will be staying, but it’s less about getting another page of results and more about getting the most recent results since the last time you executed your query. next_page will be removed since it no longer has meaning. results_per_page will become count to reflect the parameter you’ve given. We’ll be giving a method to determine if there are available remaining results from the past in your query, but not the number of possible results in your set.
Watch the [node:10734] ticket for updates on this output format.
