How do you keep track of your product reviews?

I have noticed over time that the search function on City-cost doesn't pick up certain things, particularly the 'fields' in product reviews. So, for example, if I search for a product by its brand or product name it won't come up in the search results, unless it's also written in the body or heading of the post. That is why recently I put the brand or product name in the title of the product review too, so I can find it more easily when I search. Otherwise, I won't know if I have already reviewed a product or not. Its hard to remember every review I've ever written! Have you any other hints on how to find product reviews or how to keep track of the ones you've written? I have thought about a spreadsheet, but its far too much effort!
