How do I build a query in a custom box for items that do not contain a specific tag?

The query
((Release.Name contains "GA") and (Tags.Name !contains "MVP"))

finds items with no tags and items with at least one tag that does not contain "MVP", however I want no items that contain the tag "MVP" no matter what orther tags they may or may not have.

I would have expected 

((Release.Name contains "Simics 5-15GA") and NOT (Tags.Name contains "MVP"))
((Release.Name contains "Simics 5-15GA") and ! (Tags.Name contains "MVP"))
to work but both give 
expected ")" but saw "(" instead

It would be really nice if either https://help.rallydev.com/grid-queries?basehost=https://rally1.rallydev.com or https://help.rallydev.com/use-grid-app-queries#general provided links to the full syntax of the query language and not just a list of really simple examples that don't show any complext cases (but do tell me about how to used parens many many many times).
