The "i" you pass to Hits.score is the index of the result in that Hits
object ... the "i" you pass to Searcher.explain should be the absolute
docid (the searcher has no way of knowing about your Hits, or what order
they are in).
Try something like...
searcher.explain(disjunctQuery, hits.doc(i)).toString()
