~ usage is throwing exception when used in lukeall.

What steps will reproduce the problem?
1. Create index for lucene 2.9.4 test. Use this steps to make it:
DirectoryInfo di = new DirectoryInfo(@"c:\index");
            index = FSDirectory.Open(di);
            if (!di.Exists)
            {
                IndexWriter writer = new IndexWriter(index, new WhitespaceAnalyzer(), true, IndexWriter.MaxFieldLength.LIMITED);
                writer.SetSimilarity(sim);

                // hed is the most important field, dek is secondary

                // d1 is an "ok" match for:  albino elephant
                {
                    Document d1 = new Document();
                    d1.Add(new Field("id", "d1", Field.Store.YES, Field.Index.NOT_ANALYZED)); //Field.Keyword("id", "d1"));
                    d1.Add(new Field("hed", "elephant", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("hed", "elephant"));
                    d1.Add(new Field("dek", "elephant", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("dek", "elephant"));
                    writer.AddDocument(d1);
                }

                // d2 is a "good" match for:  albino elephant
                {
                    Document d2 = new Document();
                    d2.Add(new Field("id", "d2", Field.Store.YES, Field.Index.NOT_ANALYZED)); //Field.Keyword("id", "d2"));
                    d2.Add(new Field("hed", "elephant", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("hed", "elephant"));
                    d2.Add(new Field("dek", "albino", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("dek", "albino"));
                    d2.Add(new Field("dek", "elephant", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("dek", "elephant"));
                    writer.AddDocument(d2);
                }

                // d3 is a "better" match for:  albino elephant
                {
                    Document d3 = new Document();
                    d3.Add(new Field("id", "d3", Field.Store.YES, Field.Index.NOT_ANALYZED)); //Field.Keyword("id", "d3"));
                    d3.Add(new Field("hed", "albino", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("hed", "albino"));
                    d3.Add(new Field("hed", "elephant", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("hed", "elephant"));
                    writer.AddDocument(d3);
                }

                // d4 is the "best" match for:  albino elephant
                {
                    Document d4 = new Document();
                    d4.Add(new Field("id", "d4", Field.Store.YES, Field.Index.NOT_ANALYZED)); //Field.Keyword("id", "d4"));
                    d4.Add(new Field("hed", "albino", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("hed", "albino"));
                    d4.Add(new Field("hed", "elephant", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("hed", "elephant"));
                    d4.Add(new Field("dek", "albino", Field.Store.YES, Field.Index.ANALYZED)); //Field.Text("dek", "albino"));
                    writer.AddDocument(d4);
                }

                writer.Close();
            }
            r = IndexReader.Open(index);
            s = new IndexSearcher(r);
2. Open created index as read-only in lukeall 3.1.0.
3. Perform next search: (hed:albino | dek:albino)~0.01 (hed:elephant | 
dek:elephant)~0.01

What is the expected output? What do you see instead?

message explaining what is expected.

What version of the product are you using? On what operating system?
