Search for multiple items in inventory - used to work using OR but not anymore?

We used to be able to search for multiple brands at once in inventory which made it easy to order from distributors using the OR divider.

Eg: rummikum OR “crocodile creek” OR hape

And results from all three brands would show.

Now if we enter this (with or without the " ") we get no inventory found. How can we search multiples in inventory rather than brand by brand.
