Is it OK to index a Y/N column if you have 95% N and 5% Y
and you only search for Y?

I was wondering if those 5% Y's would pop up faster compared
to RBase going row by row.

In this case, you would probably be better off removing the column entirely 
from the table and instead use a second table containing only the PK values 
from the main table that fall into the "Y" category.  This would allow you to 
quickly find the Y records without indexing overhead on the main table and 
would save you the storage space for all the "N" values in the main table.
