You need to send your existing data to elasticsearch.  
That means:

- Read from the database (`SELECT * from TABLE`)
- Convert each record to a JSON Document
- Send the json document to elasticsearch, preferably using the `_bulk` API.

Logstash can help for that (have a look at [MongoDB Logstash Integration [Solved]](https://discuss.elastic.co/t/mongodb-logstash-integration-solved/122299)). But I'd recommend modifying the application layer if possible and send data to elasticsearch in the same "transaction" as you are sending your data to the database.

I shared most of my thoughts there: [Advanced Search for Your Legacy Application - -Xmx128gb -Xms128gb](http://david.pilato.fr/blog/2015/05/09/advanced-search-for-your-legacy-application/)

Have also a look at this ["live coding" recording](https://www.elastic.co/fr/blog/how-to-add-powerful-search-existing-sql-applications-elasticsearch-video-tutorial).
