Abstract: A query application tool for a document-based database management system where data entries are stored in database tables of a database and wherein data entries are exposed through documents including data controls live linked to the database tables, includes a query arbiter responsive to a specified query to search the database tables for data entries that satisfy the specified query and generate query results. A query filter restricts the display of data entries in an active document so that only data entries in the query result that correspond with data controls in the active document are displayed.
