-The total (and finite) number of hits you can browse during pagination when using the [pagination widget](https://www.algolia.com/doc/api-reference/widgets/pagination/js/) or the [`infiniteHits` widget](#-infinitehits). If none of these widgets are used, `paginationTotalHits` is ignored.<br>

-`paginationTotalHits` has a default value of `200`.
+For example, using the `infiniteHits` widget, and a `paginationTotalHits` of 9. On the first search request 6 hits are shown, by clicking a second time on `load more` only 3 more hits are added. This is because `paginationTotalHits` is `9`.

-Example:
+Usage:
 
 ```js
 { paginationTotalHits: 50 } // default: 200
 ```
 
 `hitsPerPage` has a value of `6` by default and can [be customized](#-hitsperpage).
