Subject Re: writer.updateDocument() not working (possible bug?)
Date Tue, 13 May 2014 22:12:19 GMT

Thanks for the tip. The doc was being loaded using the method 
searcher.doc(scoreDoc.doc,getLoadFields()). Obviously, only a minority 
of fields were being loaded. However, when using the method 
searcher.doc(scoreDoc.doc), the doc appears to update when 
updateDocument(term,doc) is called. Can you confirm whether the full 
document will be returned when I call searcher.doc(scoreDoc.doc)? if 
not, what is the recommended way to get the original document from the 
index (if possible)? Perhaps, reader.document(i)?

Thanks in advance
