Description
This patch allows for optionally setting a field to use for norms factoring when scoring a MatchingAllDocumentsQuery.
From the test case:
. RAMDirectory dir = new RAMDirectory(); IndexWriter iw = new IndexWriter(dir, new StandardAnalyzer(), true, IndexWriter.MaxFieldLength.LIMITED); iw.setMaxBufferedDocs(2); // force multi-segment addDoc("one", iw, 1f); addDoc("two", iw, 20f); addDoc("three four", iw, 300f); iw.close(); IndexReader ir = IndexReader.open(dir); IndexSearcher is = new IndexSearcher(ir); ScoreDoc[] hits; // assert with norms scoring turned off hits = is.search(new MatchAllDocsQuery(), null, 1000).scoreDocs; assertEquals(3, hits.length); assertEquals("one", ir.document(hits[0].doc).get("key")); assertEquals("two", ir.document(hits[1].doc).get("key")); assertEquals("three four", ir.document(hits[2].doc).get("key")); // assert with norms scoring turned on MatchAllDocsQuery normsQuery = new MatchAllDocsQuery("key"); assertEquals(3, hits.length); // is.explain(normsQuery, hits[0].doc); hits = is.search(normsQuery, null, 1000).scoreDocs; assertEquals("three four", ir.document(hits[0].doc).get("key")); assertEquals("two", ir.document(hits[1].doc).get("key")); assertEquals("one", ir.document(hits[2].doc).get("key"));
