Searching vault with REST API for `exact` Multi-Select Lookups match.

Hello,

I am trying to query the REST API to retrieve objects that contain an exact match for a Multi-Select Lookups field.

Currently, I am using the following URL endpoint:

/objects/185?p1275=2,3

This returns all items where property 1275 includes both internal IDs 2 and 3. However, my requirement is to return only objects that contain exactly 2 and 3—excluding any that also include additional values (e.g., 1,2,3).

My current workaround involves iterating through the returned results and filtering out any that do not match exactly. However, I was wondering if there is a way to achieve this directly via the API. The search encodings documentation does not seem to offer a suitable operator for this.

I would appreciate any guidance on achieving this functionality.

Thanks in advance,
Cameron JP
