Identify Track Changes metada using Tika metadata extraction
===

I am trying to extract the metadata for a word document containing "track changes" feature in it. How can tika jar help me identify it.
Here is the code snippet

InputStream inputStream = null;
		try {
			
			Metadata metadata = new Metadata();
			inputStream = new FileInputStream("Tracked-cahngees+Hidden-text_1.doc");
			Tika tika = new Tika();
			tika.setMaxStringLength(10*1024*1024);
			ParsingReader reader = (ParsingReader)tika.parse(inputStream, metadata);
			for (String string : metadata.names()) {
				System.out.println("Metadata name extracted: "+ string +" :Value: " +metadata.get(string));
			
			}
		}catch (Exception e){
			
		}
