In my experience, multi-volume indexes are better. And not just because I used to be an academic sequestered in dusty libraries. Relying on a user's ability to select a search term is an abdication of responsibility. Reference works should always have thorough indexes. Otherwise, search effectiveness depends on a user knowing exactly what text to search for, even in cases where s/he isn't even sure what s/he's looking for.

A good index, especially one that's internally cross-referenced and behaves like a traditional thesaurus, covers all cases much better.
