Abstract: Techniques for obtaining filtering criteria used to filter a data set are described. A user interface includes a plurality of filters having an associated hierarchy. The user interface includes user interface elements corresponding to the plurality of filters with a structure in accordance with the associated hierarchy. Filtering criteria includes active filters based on selected filter values, filter state indicators, and the associated hierarchy. Enabling a parent filter causes an enabled child filter to be in the filtering criteria. Disabling the parent filter causes the child filter to be omitted from the filtering criteria. In response to a change in filtering criteria, the filtered data set may be automatically updated. User interface elements and associated filters are revealed in accordance with the hierarchy. The user interface may be customizable. Filter selections and filter state information from a session may be used to initialize a subsequent user interface session.
