True, which is why the document should be indexed with the most specific 
term.

If a user wants a comprehensive search for all information in the system 
about animals, then they should be able to search for all specific kinds 
of animals as part of that search. The search system should be able to 
distinguish between searches for items indexed with the term "animals" 
and searches for items indexed by the term "animals" or any of its 
narrower terms. This is a function of the search system, though, and 
does not require any special provision in the thesaurus structure.

The indexing term "animals" would be assigned to documents which either

a. Deal with animals in general
or
b. Deal with several types of animal, too many to index individually
or
c. Deal with a type of animal for which no more specific term exists in 
the thesaurus.

I don't think that we disagree. I was just making the point that by 
definition a mammal _is an_ animal - i.e. it inherits whatever 
characteristics distinguish an animal from any other type of concept.
