The matching in matchedValue results is done normalizing the asserted value with
the syntax associated to the requested matching rule (if any), and using the
value normalized according to the value's syntax.  As such, a search for
'-E!mv=(:caseExactMatch:=People)' fails because the asserted "People" is
compared to the normalized value of "People", which is "people".  The code needs
some reworking (a patch is coming shortly).
