 The samples include a few different dialogs that are ready to use directly, or can be subtyped to override various pieces of functionality as needed:
 * [SearchSelectRefinerDialog](Search.Dialogs/SearchSelectRefinerDialog.cs) helps users pick a refiner (facet). It's a simple wrapper around a "choice" prompt dialog that can use a shared instance of SearchQueryBuilder to ensure you don't prompt users for a field you already refined on.
-* [SearchRefineDialog](/Search.Dialogs/SearchRefineDialog.cs) allows users to see different values for a given field and select one. This is typically used for filtering later on but can be applied to any case where you want to list distinct values for a given field in the catalog and let the user pick one.

 * [SearchDialog](Search.Dialogs/SearchDialog.cs) offers a complete keyword search + refine experience over a search index, and uses the other search dialogs as building blocks. Users can explore the catalog by refining (using facets) and by using keyword search. They can also select items and review their selection. At the end of this dialog a list of one or more selected items is returned. You'll need to subtype this class and at a minimum override GetTopRefiners() (to list refiners (facets) to expore) and ToSearchHit() (to convert your index entries into a common representation that can be rendered).
 
 > You can find these dialogs in the [Search.Dialogs](Search.Dialogs/) project which is ready to reuse in your own bot.
