Nothing does uninstalled packages, as R has no means of knowing about
them!  help.search does search un-loaded packages, as in my example.  In
fact the same set as the function list (on Unix).  Looks as if something
may be wrong your end: if MASS is in some library it should be found.

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

confint(MASS)                 Confidence Intervals for Model Parameters
