I have been doing some studying on Encoded Vector Indexes with SQL.  I've been
looking at improving performance of an SQLRPGLE program running on V4R4 
that is using some rather
large files.  The documentation I have found has been limited IMO.

Have any of you experimented with/used EVI's?  And if so, what are the 
pros/cons to using
them?  Does the optimizer inform you that it is using the EVI?  Do you use 
the index
in your select statement or is the index implied?  Please advise.

Thank you in advance.
