Right, it returns the best 10 documents by score (not the first 10
docs it sees).
You could also simply use the search(Query, int) method too (which
just creates the TopDocCollector under the hood).

According to
http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/search/TopDocCollector.html
it does.
After search, simple retrieve TopDocs and read documens you need:
List<Document> result = new ArrayList<Document>(10);
for( ScoreDoc sDoc :collector.topDocs().scoreDocs) {
result.add(contentSearcher.doc(sDoc.doc));
}
And use result.

Hi
In a search I am doing, there may be thousands of hits, of which I
only want
the 10 with the highest score. Will the following code do this for
me, or
will it simply return the first 10 it finds?
TopDocCollector collector = new TopDocCollector(10);
contentSearcher.search(q, collector);
If the latter case is true (i.e. the first 10 are returned), how
can I get
it to do what I want?
Thanks,
