Those from Pichai are some global "goals" not "OKRs". Also, that's if you have some quality improvement you can use some metric. For launching new products you just have: launch new product, and then next year you can claim user growth, features adaptations, track engagement metrics, and this works for specific surface. For multiple complicated surfaces you likely can't come with single integrated metric. I even don't know how they could measure precision/recall for search, there are likely so many slices/skews/verticals/corner cases.
