So searching an image is definitely nice, but it's a tradeoff in my opinion as it takes much longer to write out an equation in equation editor (I'm very proficient btw) or the other mathematical CAD tools I use when compared to a Notebook sketch. I use them all the time, take a pic and put it in OneNote with some keywords to search.
