Elasticsearch - pagination of continuously updating data

I am new to ES and have a requirement to store real-time data streams. This is time-stamp based data.

Can anyone advise on the best way to support pagination given that the results set will be updating continuously?

I understand that Twitter and Facebook etc use cursor based pagination. I was wondering if there was a similar concept within ES?

There's nothing quite the same as a cursor, but you have a couple of options.

The easiest to use for displaying small sets of results to a user, is paging with the from parameter. See http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/pagination.html

The other option is scrolling: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-request-scroll.html

Or you can manage cursoring yourself, using the timestamps as cursors, and converting them into conditions on your query.

in Es you can achieve pagination using search type SCAN and specifying SCROLL. However you would get a snapshot meaning you will get results that exist at the moment when you run a query.
