 ## Pagy.new_from_searchkick
 
 This constructor accepts an `Searchkick::Results` as the first argument, plus the usual optional variable hash. It sets the `:items`, `:page` and `:count` pagy variables extracted/calculated out of the `Searchkick::Results` object.
 
 ```ruby
 @results = Model.search('*', page: 2; per_page: 10, ...)
-@pagy     = Pagy.new_from_searchkik(@results, ...)
+@pagy     = Pagy.new_from_searchkick(@results, ...)
 ```
 
 **Notice**: you have to take care of managing all the params manually. If you prefer to manage the pagination automatically, see below.

 ## Methods
 
-This extra adds the `pagy_searchkick` method to the `Pagy::Backend` to be used when you have to paginate a `Searchkick::Results` object. It also adds a `pagy_searchkik_get_variables` sub-method, used for easy customization of variables by overriding.

 This method is similar to the generic `pagy` method, but specialized for Searchkick. (see the [pagy doc](../api/backend.md#pagycollection-varsnil))
 
 It expects to receive a `Model.pagy_search(...)` result and returns a paginated response. You can use it in a couple of ways:
 
 ```ruby
-@pagy, @results = pagy_searchkik(Model.pagy_search(params[:q]), ...)
+@pagy, @results = pagy_searchkick(Model.pagy_search(params[:q]), ...)
 ...
 @records = @results.results
 
 # or directly with the collection you need (e.g. records)
-@pagy, @records = pagy_searchkik(Model.pagy_search(params[:q]).results, ...)
+@pagy, @records = pagy_searchkick(Model.pagy_search(params[:q]).results, ...)
 ```
 
 ### pagy_searchkick_get_vars(array)
 
-This sub-method is similar to the `pagy_get_vars` sub-method, but it is called only by the `pagy_searchkik` method. (see the [pagy_get_vars doc](../api/backend.md#pagy_get_varscollection-vars)).
