Why does the planner not use the index?

Bad form to reply to my own posting i know but -
I notice that the integer dictionary can accept MAXLEN for the longest
number that is considered a valid integer. Can i set MAXLEN for the en
dictionary to be the longest word i want indexed?
I think i'd need to create a new dictionary...?

The time has come to buy some real hardware for it.
Having read around the subject online I see the general idea is to get
as much memory and the fastest I/O possible.
