|AKA ExplodedKey() as created by Andy LeCates
A useful derivative is to restrict the length to prevent adding 1 or 2 character "words" to the key field index.
//ExplodedKey ( text ) =
Length ( Text ) > 3 ; //only explode a string down to 3 characters
ExplodedKey ( Left ( Text ; Length ( Text ) - 1 ) ) & "¶" & Text ;
