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.
