return a hash of collation key's byte.
> The given hash value produce incorrect comparison result.

> Document doc =3D new Document();
> FieldType fieldType =3D new FieldType();
> fieldType.setIndexed(true);
> fieldType.setStored(true);

> doc.add(field);
> writer.addDocument(doc);
> writer.close();
> IndexSearcher is =3D new IndexSearcher(DirectoryReader.open(ramDir));
> QueryParser qp =3D new AnalyzingQueryParser(Version.LUCENE_50,"content", =
analyzer);
