We cannot make complex filters because Shipstation just doesn't work. If you want to search up an order with TWO or more specific SKUs you won't be able to do it, because the results are all over the place. The filters "Starts with", "Contains" and "Equals" give you the same faulty result with TWO or more criteria.
You can't make a filtering system where you can group orders with the same specific SKUS either.
For Shipstation, ONE order with SKUs 54321 and 56789 is different than ONE order with SKUs 56789 and 54321.
The Group By function is also wonky as soon as you start adding more than 2 criteria.
We would love a more robust filtering system that actually worked.
