Erick, what if the search returns 100,000 hits? I'm trying to avoid loading a
large number of documents from disk (i.e. a slow operation) and then pick up
the top one. I know how to execute a search (sorted by date). Is there a way
to just load the first hit from disk? I don't know which Lucene method call
would actually load the documents from disk. searcher.doc () maybe? Thanks.
