7. A method creating a tool for generating a plurality of index elements relating to contents of an examined document; said examined document being configured according to a format; the method comprising: (a) ascertaining a first textual characteristic-set of an exemplary document for identifying a first index element for inclusion in said index; said exemplary document being configured according to said format; said first textual characteristic-set being embodied in a first textual expression in said format; said first textual expression identifying said first index element; said ascertaining being effected by: (1) selecting a particular representative textual characteristic-set from a store of a plurality of representative textual characteristic-sets; said particular representative textual characteristic-set being related to a selected index element in said index; (2) searching said exemplary document for occurrences of said particular representative textual characteristic-set; (3) reviewing said occurrences to determine whether said occurrences satisfactorily identify an instance of said selected index element; (4) if said occurrences do not satisfactorily identify an instance of said selected index element, selecting a next particular representative textual characteristic-set from said store of a plurality of representative textual characteristic-sets; said next particular representative textual characteristic-set being related to a selected index element in said index, and repeating steps (2) through (3) using said next textual characteristic-set; (5) if said occurrences satisfactorily identify an instance of said selected index element, storing said particular representative textual characteristic-set and deciding whether another selected index element of said index is desired; (6) if another selected index element is desired, repeating steps (1) through (5); and (7) if another selected index element is not desired, terminating said ascertaining; (b) expressing said first textual characteristic-set in a computer-executable code; (c) saving said computer-executable code in a data store; (d) if another index element is desired for inclusion in said index; ascertaining a next textual characteristic-set for identifying a next index element for inclusion in said index; said next textual characteristic-set being embodied in a next textual expression in said format; said next textual expression identifying said next index element; and repeating steps (b) through (c); and (e) if no other index element is desired for inclusion in said index; terminating the method.

A method creating a tool for generating a plurality of index elements relating to contents of an examined document as recited in claim 7 wherein said storing includes saving said particular representative textual characteristic-set in a data store available for employment during later practices of the method.
