R help - Jan 2008 - help.search and indexing

Dear expeRt,

I occasionally use help.search() function to find appropriate  
functions in R.
Whenever committing help.search() after rerunning R, it takes so much  
time to find help (around 2 minutes).
Is there any way to make it faster in help.search()?
I think indexing help database is one of the solution, but i don't  
know how to do.

Best,
Dong-hyun Oh

It is already done for each package, at installation.

What version of R?  This is much faster in recent versions, including 
R-devel.  The latter takes only 3 seconds on my system, with 1500 packages 
installed.  It is likely the problem is reading the package indices on 
your system, especially if they are on a non-local or slow file system.
Note that subsequent queries in the session make use of the already-built 
database (if relevant).
