>The VFP 5.0 Developer's Guide states at page 396, parag. 5, " Avoid using indexes on fields that contain only a few discrete values such as a logical field"
>
>So then why should having an index based on deleted() be considered indexing effectively using Rushmore (see DG page 400)
>
>Aren't these two very similar in their respective context (i.e.: few discrete values .T. or .F.).

>Why should it be OK for deleted() and not for the other(s)?
