They should be in the documents.  If you have lots of them, no, you won't be
able to get them all with decent performance.

You have a problem.  You might be able to use real-time updates in Lucene to
get something close to what you want. But it is probably better to
re-examine the requirements.

Any idea / suggestions?

Can you bend some of the requirements?  Is it really necessary to sort on

Do you have a relatively small number of objects in your result sets?  How
long would it take to retrieve the sorting info from a few hundred or even a
few thousand items?
