Fix stripping of large indexed ordered properties

Currently, the ordered indexed properties are truncated at the max length supported by lucene at 32766 in the LuceneDocumentMaker.

The problem is lucene uses a class BytesRef to represent strings which converts it to UTF-8. It then uses the length from this converted string to enforce the limit. The transformation between java unicode string to utf-8 can cause the length to increase for non-ascii characters.
