At present, (directory and IA5) substrings indexing only generates/uses
indices for "initial" and "final" strings.  Indexing for "any" strings
is not implemented (and isn't high on my priority list).

Also, note that a substring assertion of mail is undefined
(no substring matching rule provided in schema), so indexing
really doesn't matter.  The server should optimize this to ALLIDS
quickly.
