Abstract: A system and method for filtering an already obtained information resource (“document”) for display is described, including identifying a target portion of the information resource; dividing the data of the target portion into elements of a set; receiving one or more search requests as a filter specification; interpreting the filter specification as a Boolean logic expression; evaluating the elements of the set based on the Boolean logic expression, in an ongoing manner, each time the filter specification is entered or modified; and dynamically re-rendering the display, upon each such entry or modification of the filter specification, with all elements not matching the logic expression removed from the display of the target portion, providing the user with a “shrinking document” more likely to contain just the information being looked for.

Abstract: A system and method for filtering data is provided, including identifying a target portion of a data source, dividing the target portion into one or more elements of a set, receiving one or more search requests as a filter specification, interpreting the filter specification as a Boolean logic expression, evaluating the elements of the set based on the Boolean expression, and displaying the elements which match the search request on a display.
