Hello,

In my use case, each case has a `product_id` which is a business data attribute and related to our internal business logic.

I’m looking for a way to get the `case_id` given a `product_id`.

I did manage to do the other way around, meaning getting the `product_id` given a `case_id` using the case context.

Indeed if I search for the case context I get a response with the form described in the documentation [https://documentation.bonitasoft.com/?hash=retrieve-the-case-context&page=bpm-api#toc25](https://documentation.bonitasoft.com/?hash=retrieve-the-case-context&page=bpm-api#toc25)

I then can get the `storageId` and the `type`and match them with my business data. `storageId` would then match `persistenceId` and `type`, `businessDataType`.

But how can I search cases by context using `storageId` and `type` ?

Thanks for you answers.
