Script to search a large file with a list of terms in another file

Hi-

I am trying to search a large file with a number of different search terms that are listed one per line in 3 different files. Most importantly I need to be able to do a case insensitive search.
I have tried just using egrep -f but it doesn't seam to be able to handle the -i option when selecting a file for the search terms.

Any suggestions?
