+splitIndex.sharedIndexExpire::
+       When the split index feature is used, shared index files that
+       were not modified since the time this variable specifies will
+       be removed when a new shared index file is created. The value
+       "now" expires all entries immediately, and "never" suppresses
+       expiration altogether.
+       The default value is "2.weeks.ago".
+       Note that a shared index file is considered modified (for the
+       purpose of expiration) each time a new split-index file is
+       created based on it.
