Abstract: Described are systems and methods that facilitate visual search for and price filtering of information. For example, rather than requiring a user to select a pre-defined price range (e.g., “under $25,” $25 to $50,” “$50 to $100”) for filtering, a user may price filter search results by specifying a single price filtering value around which the search results are filtered. The range around the single price filtering value is dynamically selected based on, for example, the search results being filtered, the past purchase history of the user, past user search history, etc.
