I believe a similar question was posted before. But my question is specific to Java SDK version 1.4 as to whether there is a way (be it straightforward or a hack) to retrieve a list of all keys from a bucket. I see that couchbase provides N1QL queries in the higher SDKs for this purpose. But for various reasons, our team decided to continue using the older version for now. I need this feature to autosuggest a list of keys based on user’s keyword search via a REST api call. Any recommendation on how to achieve this with couchbase Java SDK 1.4?
