Subject Re: Quick question on indexing an existing index
Date Fri, 15 Oct 2010 13:04:16 GMT
Why don't you simply index the source content which you used to build index2 into index1, i.e.
have your "tool" index to both? You won't save anything on trying to extract that content
from an existing index. But of course, you COULD write yourself a tool which extracts all
stored fields for all documents in index2, transform it into docs which fit in index1 and
then insert them. But how will you support deletes etc?
