In earlier discussions, several of us suggested that we should like to have
a "thesaurus display" function, i.e. be able to see in alphabetical order
all key words used in earlier records.

Upon reflexion, I should like this to be slightly more sophisticated.
Frequently one assigns key words that are part of some conceptual hierarchy
(eg. animals - mammals - cats). While this may seem pleonastic, it is
helpful in that it allows searches of different generality. A request for
"mammals" is simpler to frame than one for "cats or dogs or horses or cows
or ."

It would be helpful if such hierarchical links among key words could be
recorded and if, when using one such word, either during indexing (creation
of records) or during searches, one had the possibility of displaying
"ascendants" and "descendants".
