It depends..., If about 95% of all the codes or names are the same and you only search for this code or name, you better of without it.

This is precisely the matter with the TAG on DELETED(). If the table contains none or only few deleted records, VFP reads the DELETED() index to filter out records, but it comes to the conclusion that it only can filter out a few deleted() records. After this VFP has to read the records anyway. This makes no sense.

Let's take for example a table that contains a column articleno, If all the values in this column are the same. An index on this column can only degrade performance. The index slows down performance. Just test it and you'll come to the same conclusion.
