Ron,
Bill,
SRE,

Well, I think I have made the necessary modifications to
index.c in order to store the positions of the words
in the index file.
Now, I am going to make some changes to search.c for
implementing the "phrase search" but I am working
with 1.3.2 code. So, if there is a more recent version,
can anybody send it to me?

Have a nice day
