So, I just thought of documenting various steps so that other can be benefited. So, in my scenario, I had to select some X records from one couchbase bucket and migrate them to another bucket. This was really easy. I wrote a N1QL query, added some WHERE clauses, and thats, done! All the selected records were migrated from one bucket to another. Here comes the complexity.

So, now I had to find some work around, and this is what I came up with (someone may have better solution for this scenario): 1. Create a "tmp" bucket and ...

Couchbase Server (A.K.A. Couchbase) is open source , NoSQL , document oriented database that stores JSON documents. Couchbase has recently introduced a new feature - Full Text Search ( FTS ). This feature is currently a Developer Preview Version (as of Aug 24, 2017). Couchbase has provided decent documentation for FTS which can be access here .
