Does it work for numeric fields too? I am working with 2.9.0 and the
following code gives extra values:
@Test
public void distinct() throws Exception {
RAMDirectory directory = new RAMDirectory();
IndexWriter writer = new IndexWriter(directory, new
WhitespaceAnalyzer(), true, IndexWriter.MaxFieldLength.UNLIMITED);
for (int l = -2; l <= 2; l++) {
Document doc = new Document();
doc.add(new Field("text", "the big brown", Field.Store.NO,
Field.Index.ANALYZED));
doc.add(new NumericField("trie", Field.Store.NO,
true).setIntValue(l));
writer.addDocument(doc);
}
writer.close();
IndexReader reader = IndexReader.open(directory, true);
TermEnum termEnum = reader.terms(new Term("trie", ""));
Term next = termEnum.term();
List<Integer> ints = new ArrayList<Integer>();
while (next != null && next.field().equals("trie")) {
ints.add(NumericUtils.prefixCodedToInt(next.text()));
next = termEnum.next() ? termEnum.term() : null;
}
reader.close();
log.info(ints.toString());
}
==> [-2, -1, 0, 1, 2, -16, 0, -256, 0, -4096, 0, -65536, 0, -1048576, 0,
-16777216, 0, -268435456, 0]
Is there a way to make this work?
