Elastic search over an already existing lucene index

Elastic Stack Elasticsearch
1

I have a system that uses lucene. Now for a few reasons I would like
to add a distributed search feature over it.

The question is can I use the existing lucene index created by the
IndexWriter of lucene, for searching with elastic search or should I
create a new index using ES's IndexWriter. Do note that the Lucene
version we have used is 2.3.1. Any help would be appreciated.

You will need to reindex into Elasticsearch

Dear clint,

     Thanks for your answer. The idea behind me asking if I could

re-use the same index is that, I didn't want to disturb the
already existing lucene instance. If the only way is to re-index, then I
will have to look for some other option.

     Just want to know if there is any other way other than re-indexing.

No, you need to reindex.
