[Feature] Search with Quotes for Exact Match

Currently, the main snap search is an OR search when there are multiple words. If i search for the phrase big dog, I get posts including big and posts including dog.

Adding quotes does not seem to modify this, i.e. "big dog" results in the same.

My suggestion is that a search for "big dog" should only result in snaps that contain the exact phrase, big dog and not ones that contain one or more of its constituent parts.

Too many big dogs, but you get the idea.
