Dear all,
Hi,
I was wondering, is it possible to re-index Solr 6.0 data in case of
store=false? I am using Solr as a secondary datastore, and for the sake of
space efficiency all the fields (except id) are considered as store=false.
Currently, due to some changes in application business, Solr schema should
change, and in order to see the effect of changing schema on old data, I
have to do the re-index process.  I know that one way of re-indexing in
Solr is reading data from one collection (core) and inserting that to
another one, but this solution is not possible for store=false fields, and
re-indexing the whole data through primary datastore is kind of costly, so
I would be grateful if somebody could introduce other way of re-indexing
the whole data without using another datastore.

Sincerely,
