overview-summary.html: no suitable method for isearcher.search(query, null, 1000) [LUCENE-7820]

[asfimport]

The example in overview-summary.html includes the lines

    IndexSearcher isearcher = new IndexSearcher(ireader);
...
    ScoreDoc[] hits = isearcher.search(query, null, 1000).scoreDocs;

However javac complains there is no suitable method for search(Query,<null>,int).
The example runs with the null removed.

-    ScoreDoc[] hits = isearcher.search(query, null, 1000).scoreDocs;
+    ScoreDoc[] hits = isearcher.search(query, 1000).scoreDocs;
