Search for assets with multiple CATEGORIES as the search terms

we would like to search our iRAM community, via the web client, to find assets that contain any of a list of categories.

we have a category called "Blue Communities / Owning Blue Community", which is an exclusive category, only one selection can be applied to an asset

So we want something search keyword like the following...

category:("Canada Corporate Blue Community" OR "Canada Services Blue Community")

but that does not seem to be working.  Can you help me with the search query structure ?

Thank you
