Filtering accelerated data models by metadata field

[severt]

We are trying to implement a security solution on splunk for a client that has multiple data sources on multiple countries. We want to ingest data from all these countries to the same splunk instance and we've decided to separate each countrie's data by adding a metadata field. Each country has its own user and can only see their data. We achieved this by defining a new role and creating a search filter to set search restrictions for this role. The problem is that this security solution uses accelerated data models and this way of filtering is not working on accelerated data models, where a country can see other countries data. 

Is there any kind of search that works properly on accelerated data models where i can filter data by a metadata field?
