I think the 'better way' may involve a new design.  What is the logic of 
how records are allocated?  Is there any structured layout behind them?  
If not, might there be a way to do this?

If the answer is still no, you could design an indexing system to help 
you look up the strings.   The fastest way would probably be a suffix 
tree (although it's going to take up a LOT of disk space for something 
this big).  I have some code to build a tree, although it wouldn't work 
for your case, because it's all done in memory, but it could be done in 
files fairly easily.  I'll see if I can get it modified in the next few 
days or so.
