Isn't top_hits aggregration pageable? See the "from" parameter listed on the page:
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-metrics-top-hits-aggregation.html Certainly you don't want to page through everything (you want scan/scroll for that), but adequate paging for most search uses. Or do you want to just eliminate duplicate authors only in one page (ie set of 10) of results? -Doug On Tuesday, December 9, 2014, Travis sturzl <travisstu...@gmail.com> wrote: > I'm trying to find a way to prevent multiple posts from appearing in > search results that are from the same author.
