Lucidworks Fusion, our development platform, for building AI-powered search applications, ships with faceting ready to deploy immediately.
As Fusion receives a query from a user and assembles a set of results it looks at common fields across the results and generates facets for them automatically. So a product catalog search for “women polo shirts” will include facets for all the colors of shirts and the sizes available and even price range of the different items. Powerful caching technology makes the addition of facet fast and instant to a search query result returned.
