+## Deep Pagination
+
+By default, Elasticsearch limits pagination to the first 10,000 results [for performance](https://www.elastic.co/guide/en/elasticsearch/guide/current/pagination.html). We don’t recommend changing this, but if you need to, you can use:
+
+```ruby
+class Product < ApplicationRecord
+  searchkick settings: {index: {max_result_window: 1000000000}}
+end
+```
+
+And search with:
+
+```ruby
+Product.search("pears", limit: 1000000000, body_options: {track_total_hits: true})
+```
