Categorization of routines (string,file etc) would be a good place to start.
I have thought about this before (for chm), but while the CHM format
supports this (building e.g. a list of string routines over multiple
independantly compiled CHMs), the Windows viewer's support for this is too
basic, and the *nix viewers are even worse.

It seems to be functionality intended for MSDN that never was finished
because of the move to later formats.

CHM has a basic phrase indexer, and it operates on the html. The search part
is maybe part of the viewer, and one would have to see how complex it is. 
(Iow if the complexity is in index or search, if the search is relative
simple one could look at kchmviewer)
