I think you need to have a term on public documents as well, and take  
measures to make sure that is always in your query. Or you could  
write a MatchDecider that decides if the query should see private  
documents or not I suppose.

By default a boolean term not being in the query does not invalidate  
the document. (Its presence in a query mandatories it in the  
documents, but not the opposite afaik)
