Sounds like your relationship is invalid in some way to me. A find in account name should find for your queried account if properly related.
Make sure that:
1) FK and PK keys are the same field type (EG text with UUID, or number with auto-enter serial).
2) Properly related in the relationship graph
3) Data is filled in appropriately with matching FK and PK keys.
On your accounts table layout, if you make a portal to operations, can you see those related records?
