Carrot2

With the Carrot2 library, you can move beyond simple ranked lists. Its core clustering engine processes search results to build a coherent, folder-like structure of related topics. This is powered by a suite of algorithms that intelligently determine document similarity and label clusters effectively. The result is a more navigable and insightful presentation of information, empowering end-users to explore by concept rather than sifting through pages of results. It's a key solution for adding analytical depth to any search functionality.
