Lucene Numeric Range Query Returning No Results / Unexpected Results - lucene.net

Question

I'm using Lucene .NET v3 on .NET 4.5. I'm not sure why I'm getting incorrect results in my query. Here's a simple test app:
static class Program
{
static Document MakeDocument(String rcaName, int statusCode)
{
var doc = new Document();
doc.Add(new Field("RCAName", rcaName, Field.Store.YES, Field.Index.NO));
doc.Add(new Field("ActionId", Guid.NewGuid().ToString(), Field.Store.YES, Field.Index.NOT_ANALYZED));
var status = new NumericField("Status", Field.Store.YES, true);
status.SetLongValue(statusCode);
doc.Add(status);
return doc;
}
static void Main()
{
var dir = new SimpleFSDirectory(new DirectoryInfo("C:/Sologic/temp/bsindex"));
// var analyzer = new SologicAnalyzer() { StopWords = StopAnalyzer.ENGLISH_STOP_WORDS_SET };
var analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_30);
using (var writer = new Lucene.Net.Index.IndexWriter(dir, analyzer, true, Lucene.Net.Index.IndexWriter.MaxFieldLength.UNLIMITED))
{
writer.AddDocument(MakeDocument("RCA 1", 2));
writer.AddDocument(MakeDocument("RCA 2", 4));
writer.AddDocument(MakeDocument("RCA 3", 2));
writer.AddDocument(MakeDocument("RCA 4", 4));
}
var searcher = new Lucene.Net.Search.IndexSearcher(IndexReader.Open(dir, true));
var query = new Lucene.Net.QueryParsers.QueryParser(Lucene.Net.Util.Version.LUCENE_30, "Status", analyzer).Parse("2");
var hits = searcher.Search(query, 100);
Console.WriteLine(hits.TotalHits);
Console.Read();
}
}
When I open the index with luke, I run the following queries:
Status:[2 TO 2] - 0
Status:[4 TO 4] - 0
Status:[0 TO 4] - 4
Status:[0 TO 2] - 4
Status:[0 TO 0] - 0
I'm a bit baffled. Anyone see what I'm doing wrong?

Answer 1

Two things:
A.) You're setting a long value with an int. I'm guessing this probably is leading to some wonky mishap a level below. Stop doing that.
status.SetLongValue(statusCode);
becomes
status.SetIntValue(statusCode);
B.) Don't parse a string to get an int. Basically QueryParser is the wrong choice here. Where you have:
var query = new Lucene.Net.QueryParsers.QueryParser(Lucene.Net.Util.Version.LUCENE_30, "Status", analyzer).Parse("2");
you need
var query = NumericRangeQuery.NewIntRange("Status", 4, 4, true, true);
So now your problem is solved, but I still get no results in luke. Perhaps it's due to a misunderstanding of the tool itself. Anyhow, happy trails buddy.
