Could you add a way to search for specific keywords via a text query? For example I could search for my last oil change by typing in "Oil Change" into the query, since that is how I enter the keyword in the note?
I understand you can browse your history then click on the keyword, but for some of my notes, such as cabin filter maintenece and tire rotation, there can several fill ups between each, so it is tedious to try to find the notes that contain that specifically.
That's a good idea, we'll add this to our long to do list. In the meantime you might try exporting everything and opening it in a program like Excel. You should be able to use Excel's Find feature to spot specific fuel-ups and notes by keyword.
You could also tag your oil changes with "oilchange" or "oil" and then use tags to find it again. But I agree that having a text search would be more convenient.
That is what I do. I have two tags that I use: "roadtrip" and "maintenance," and the two of those help me sort through everything I need to keep track of. Remember that the tag is not part of the text of the note, so you can write an independent text description. Also using ctrl-F (on PC) when viewing all fuel-ups (or one page at least) can make it easier to find notes if you haven't used tags.
