Faceted Counted Search

Better search experience with facet driven navigation and search refinement

Forward Search loves facets. Add facets to your documents for better search experience, easier search driven navigation and result refinement, and ultimately because that's how people think. 

Facets are keywords, tags, categories, properties, groups, classes,-  yes any document descriptor that can be enumerated into a finite number of labelled values. Add a field for each facet to your documents, and have Forward Search deliver the values (the options) and counts of occurences for each facet along with the results. Then you can present the user with the value options in each facet, including the count of items that matches each option. That's what we call "Facet Counted Search".
