Has anyone played with EVIs? They look interesting and may be a good use for web applications that can sort/select by many different fields or anything using dynamic SQL. Yes I have. They work best when built over data that would have a natural limit on the number of key entries in the table. An example would be the state field or county. Social security number would be a very bad choice because there is one per unique individual for instance. Depending on the size of the database I have used the first three characters of the zip code in the past. That way a location lookup can use the EVI to eliminate most of the rows in query right away without even looking at the other indices.
