Discovery is going to war
"First and foremost, the defining factor of Roddenberry’s vision is the optimistic view of the future. He envisioned a world where all species, all races came together to not only make our world better, but to make every world better. I think that is something that can never be lost in Trek. Once you lose that, you lose the essence of what Star Trek is.
That being said…we live in very different times. Every day we look at the news and it is hard. It is hard to see what we see. I think now more than ever Trek is needed as a reminder of what we can be and the best of who we can be. Star Trek has always been a mirror to the time it reflected and right now the idea that – the question is how do you preserve and protect what Starfleet is in the weight of challenge like war and the things that have to be done in war is a very interesting and dramatic problem. And it feels like a very topical one given the world where where we live now."

According to the above, expect any type of discoveries that you believe qualify as such or prefer the show to focus on—seeking-out, accidentally-stumbling-upon or of-opportunity—to happen within the war theme, unless it does not span all seasons..
