Perhaps a non-elegant solution would be to create a ModifiedAge (and perhaps
a CreatedAge) property for a Topic. If this were to be a decimal value based
on 24 hour periods, or portion thereof, since the object had been modified
then this would allow an easy selection when only LastModified is used as
the selection criteria. It would mean some pages WikiTalk would need to be
redone to use the new feature.
It does not solve the problem of a Sort based on LastModified as the issue
here is one of sort efficiency. The more items in the selection criteria the
less efficient this sort is. This indicates that the cache should have a
sorted list of topics by LastModified, which should probably be implemented
using a balanced tree algorithm for speed.
The last time I implemented such an algorithm was over 20 years ago. Maybe
somebody else is more familiar with the current state of the art of sorting?
