The Hits class was deprecated at some point and has been removed from recent releases.
The 2.9.3 javadoc at http://lucene.apache.org/java/2_9_3/api/core/org/apache/lucene/search/Hits.html shows a little code sample TopDocs topDocs = searcher.search(query, numHits); ScoreDoc[] hits = topDocs.scoreDocs; for (int i = 0; i < hits.length; i++) { int docId = hits[i].doc; Document d = searcher.doc(docId); // do something with current hit ... you just need to replace numHits with a suitable value e.g. 1223 and replace the for loop with something like int docId = hits[57].doc; Document d57 = searcher.doc(docId); docId = hits[1223].doc; Document d1223 = searcher.doc(docId); Higher values for numHits may have adverse effects on performance, but if you need them, you need them. -- Ian.
