Facets allow users to refine their search results by selecting appropriate filters based on the field values. These filters are used to fine-tune the search results and category listings without scrolling through innumerable pages. For example, in an eCommerce search, options to select the price range for the product or to filter the results based on the color of the product are provided. 

SearchAssist application allows you to configure and manage facets. You can mark any indexed fields as a facet. Enabling the facet allows the search user to view the filters associated with the search results and also the count of matched results in the filter.

The SearchAssist application allows you to define two types of facets: 

• Range Facet is used for filter attributes that have a defined range of values such as price, age, etc. It returns the result within the selected range. In product search scenarios, the Range facet is used to choose the price value of a product. For example, on an e-commerce website, you can use Range Facets to show all smartphones in the range of $1000 to $20000.
• Value Facet is used for filter attributes that are treated as labels such as colors, gender, etc.

You can configure both single-select and multi-select facets. The multi-select facet allows you to customize whether a user can select only a single item or multiple items in a filter. You can also customize the order in which the filters are displayed to the user by simply drag and drop operation.
