At WWDC 2018, Apple announced a new photo find feature to take the work out of surfacing all the great shots you want to share. 

"This year we're making Photos even better, and it starts with search," said Craig Federighi, Apple's senior vice president of software engineering. "In iOS 12, search now starts working for you even before you start typing with search suggestions. It will highlight things for you like key moments and people who are important to you."
