How to search Total board views from Bulk Data for a unique user?

Some materials for Bulk data:

API:https://developer.khoros.com/khoroscommunitydevdocs/reference/lithium-bulk-data-api

I've already saved the data to my local DB.

I'd like to know how to search total board views for a unique user? I tried to set conditions like user_uid ,aciton_key ,message_type  and so on.  But the result still wrong.
