Yandex.Direct and minus words?

Question

contextual advertising

Actually, I got a little confused, after Yandex itself sometimes places minus words, then I'm interested in the following question:

1) wedding procession Simferopol -! in
2) wedding procession - Simferopol

are these phrases equivalent? let's say if I want the ad to be shown for the search phrase: "wedding procession" - will I see the ad in the first case? And another question:

wedding cortege + simferopol

- in such cases, how my ads will behave, since on the basis of manuals - a bit confusing situation, I want to figure it out using a real example.
what if I want to see an ad for: wedding procession simferopol and wedding procession? but definitely not separate words, such as a cortege or wedding or Simferopol
