Thanks. That clarifies it.

I am really not up to the task, though, and will really have rely on your expertise. Please take a look at: http://www.indiana.edu/~libej/new.html . All I really need for now is to be able to search for multiple words that are not adjacent to each other in the title field.

I don't want to make any changes in the letter_search subroutine, which is exactly want I want.

Thanks a lot.
