Indeed Faceted Navigation

Job search engine Indeed offers faceted search filtering in their results. Facets include useful filtering criteria such as job title, salary range estimate, company, location, and job type. Filters beneath any facet may be selected at any point while viewing the results, and removed in an ad-hoc manner regardless of the order selected. Users may also remove all filtering to return to original results.
