I use Notes extensively for my studies. I like its iCloud syncing and simplicity. Only thing that's been bugging me since the beginning is the search function. It doesn't always locate the right location (sometimes some weird random spot) and when it does work there's no next or previous button like there is in the Safari search function. It just gives me the first instance of the word and then I'm SOL. And scrolling through Notes doesn't help. Not only does the next instance not get highlighted but even if it did, you can't realistically scroll through hundreds and hundreds of lines. I even tried iOS Spotlight just now and all it did was open Notes to some random spot that has nothing to do with the word I searched for. These issues have been here since iPhone 4 to iPhone 6.
