Get results that are missing an attribute

Hi,

I am working with Instantsearch.js to build an algolia app using Angular. Our indice is basically a giant product catalog. The main user for this page is using aglolgia to search the catalog so they can edit some data about the product, and then send it back to the db. However, we now have a use case where we need algolia to give us results that missing an attribute. I am not seeing anything out there for Instantsearch.js that would give us this functionality.

For example, I am looking for products that have the word ‘phone’ in it but are missing the ‘device’ attribute. This way, the user could do a bulk update and add ‘device’ to all the relevant results returned from alogolia.

Is this possible? My use case seems similar to this: Missing Index Attributes
