Hi,
you wouldn’t use another view to get the documents by ID, you would do a multiget, which is way faster.
Or you use one of the SDKs which have an include_docs parameter, which will do it for you automatically when a spatial view is queried. Please note that currently the support for spatial views within the SDKs is still in development, so you need to check whether the SDK you use already supports it.
Cheers,
Volker
