Searchable General Notes section

I would love a section where I can keep general notes and be able to search them later. The main thing I keep coming up against is: When did I last include _____ in my day's food? Usually, I'm looking for a restaurant meal that I entered manually, then when I eat there again (same meal as before) I have to step backward through the calendar, day by tedious day, until I either find the last time I ate there or just plain give up and enter it all over again (and maybe not the same as I did previously)! You CM people keep doing amazing things and so I hope this will be doable some time in the future. THANKS!
