Perhaps  Persistent objects could be made to follow the observer pattern
wrt Indexes.  That is when an object is first added to an Index any update
to that object could trigger a reindex call on any 'observers' automagically.

This reindex call could have the field changed as a parameter to help optimize
away needless indexing checks.

Just thinking with my fingers...
