Boolean logic is there, any is effectively an "or" and multiple conditions an "and", it's just not uniformly applicable. Which makes notebooks clunky 2nd class citizens in the search algorithm

Yes, that's unfortunately and arbitrarily limiting. 

Yes, evidently  Was hoping it was more orthogonal. Sorry it wasn't clarified earlier. 

Thanks but that's basically just searching on two tags (after assigning everything in notebook x to a tag)... my use case is a single search, that I can put in shortcuts that would combine:

notebook:x  ... let's say this has 1 note

notebook:y ... has a note with tag:z

The search:

any: notebook:x tag:z

which returns the notes in notebook x and all the notes in notebook:y or any other notebook, that has tag:z

I would like to find notes which are either in notebook x or have tag y, I haven't found a way to do this with the search syntax. Has anyone found a method? Thanks!
