The Hits class was deprecated at some point and has been removed from

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.

I have an application where I would like to pick one document from somewhere
in the list of search results. For example, I would like to retrieve one of
the results at rank 57, another at rank 1223, etc. I'm not real clear on
how to do it.
I have seen some things on simulating pagination with Lucene, some code on
using hitlists and some comments on hitlists being deprecated.
I have seen the class TopDocsCollector and the method
|*topDocs
<http://lucene.apache.org/java/2_9_3/api/core/org/apache/lucene/search/TopDocsCollector.html#topDocs%28int,%20int%29>*(int
start, int howMany)|
Returns the documents in the rage [start ..
I can see using topDocs with howMany = 1, but I'm wondering whether that
means that the system iterates over the entire return list until it finds
the the one at rank start?
Is this the best way to do it?
I'm using pyLucene 2.9 on Ubuntu 10.04.
Thanks for any pointers.
