Thanks Jorg but I didn't able to migrate the lucene indexes to ES even
after trying what you have suggested. Maybe, I need to follow some more
steps.
I am not getting any error but the search is not showing any docs/records.

Otis,
I am not sure how many of our customers will accept to re-index the whole
data as they are using it since long, although I am trying to convince my
Senior Product Management to keep both Lucene and ES. Some old customers
can think to migrate to ES if they need better real-time performance

I can not tell if it will work, but if you could translate your xml mapping
into an Elasticsearch mapping it would be great.
The next steps would be to create an empty index with the mapping, using 1

Thanks Jorg for the guidance and I have am trying the suggested approach #1
and I have further question on it.
As you mentioned - *"- a custom written tool could traverse the segments
and extract field information and build a rudimentary mapping (without

It is almost impossible to use just binary-only Lucene index for migration,
because Elasticsearch needs additional info which is not available in
Lucene. The only method is to reindex data over the Elasticsearch API.
There is a bumpy road but I don't know if one ever tried that:

Hi All,
I have an embedded Search Engine in our product which is based on Lucene
4.8.1 and now I would like to migrate it to latest ElasticSearch 1.4 for
better distributed support (sharding and replication, mainly). Could you
guide me how one should migrate the existing indexes created by Luce
