If the issue is too much data, then one solution would be to prune the data, for example by using the |fields command to limit the data to that which is actually required, rather than extracting and returning all fields.
The real question here is "what is that user trying to find out, and what is the most effective way of getting that information for them?"
If the active directory index events are too chatty to be useful, then that index should be eliminated from the search. On the other hand, if some subset of the information is useful and needs to be retrieved, then a narrowly-tailored search needs to be developed that gives the information that is essential to the role/function doing the search, and no more.
