Re: deleting with sorting and max document
You don't do it with deleteDocuments() but with
IndexReader.deleteDocument(int docNum), as I said.
To spell it out a bit more:
Execute a search to get a list of document ids,
searching/sorting/whatever as you wish.
Then loop th
query, but as args in the index searcher.

Re: deleting with sorting and max document
You can get a list of document ids via your search/sort call and call
IndexReader.deleteDocument(int docNum) for each one.

Vincent,
I think you may be looking for the following method:
