@Simon I'm just wondering: If the document IDs are per segment how
does it work if I call, int) and get TopDocs
referencing ScoreDocs which contain document IDs? What happens if
there are two matching documents in different segments? How does
Lucene know which segment is meant if I call Searcher.doc(docId) with
some docId from the search result?
