Search api autocomplete - how to show search form? I use Search Api with Search api autocomplete module.

I made configuration of autocomplete module on Search Api page, but I do not see block for input.

Should I config anything else for it?
There should be a block named Search box in admin/structure/block, i think it is the search box by default of drupal.

Remember that this block uses a view that returns a JSON, you can specify which view to use entering admin/config/search/search_autocomplete
