fess.search index not following doc.json

(from github.com/freestyle68)
Hi,

If I change

/usr/share/fess/app/WEB-INF/classes/fess_indices/fess/doc.json

then delete fess.search index and restart fess, the new index does not take the new mappings, as I can see from

Dashboard --> fess.search --> show mapping

There is a way to change this?

  1. Change doc.json
  2. Start Reindex with Update Aliases at Upgrade page
  3. Check the new index
  4. Delete the old index

Tested and working.
Thank you very much!
