I have an elasticsearch2.3.4. cluster. The index source has some filed store parameter false.  
For example, when index a pdf document, I have a mapping for its author,name,path and content, but the content field's store parameter is false, I need this field just for searching, the pdf is stored on other file store server.  
When I upgrade the elasticsearh, I just fount the reindex api cannot reindex the content field,  
So is there an option I can upgrade the elasticsearch?
