Not only is it nice, but we do already have it, twice, in fact!

There are two search/browse facilities for all current libraries (and I
mean that, not packages), namely help.search() and the Java-based HTML
search.  Try them some time!

> help.search("confidence interval")
Help files with alias or title matching `confidence interval':
Type `?FOO' to inspect entry `FOO(PKG) TITLE'.

confint(MASS)           Confidence Intervals for Model Parameters
[...]

So why would removing an *index* affect the ability to search?
