Moving from iMatch to Bridge

[AFairley]

I want to take my iMatch categories and import them into Bridge as the Bridge keyword list, keeping the same hierarchichal structure.

I want to then batch assign the keywords to the images in Bridge the match their iMatch categories.

Can someone point me to a resource to help with this?

BTW, is there any way to do true boolean searching on Bridge Keywords, I haven't seen it.

Thanks!
