Do I need to unload/reload the file?

[Witkopp, Richard]

Well, sorta. Changing the dictionary is only a map
that Powerhouse uses. It doesn't affect that data itself
at all. You'll need to CONVERT the file, which will create
an index on it. Just be careful not to use Powerhouse's
generated .fdl because it results in a very inefficient
file.
