keywords are from a prescribed list of categories (in R_HOME/doc/KEYWORDS).

The Windows help systems for R already do that on a pre-package basis.
It is not prohibitively slow given the OS-level support, but it does
take up quite a bit of space as the indices are built with the packages
(and building base from the HTML files takes ca 25 secs then).

It is the sort of thing which help.search might do, if re-written
in a compiled language.  Building its present database is quite slow
and an FTS one would be very much slower in R.
