Since search results contain many more notes than the ones that contain search terms, I want to thank you for displaying bold face the notes that contain the search terms--so you don't just get a list of (child?) notes, hidden somewhere among which may the one(s) that contain the search terms.
Very minor point/suggestion/question: Even when most or all search results are child notes, this feature only works when I specify search "notes" rather than "child notes" in the search options.
