I too have been trying since windows 3.1 cardminder to find such a tool, quick, flexible and most importantly with a way to "instant recall" content. To make a long story short, currently after having used Google "Keep" and "Save to Keep" extension - I am pretty happy with it for allot of stuff from cooking recipes to groceries shopping lists to technical articles and web sites.
I love it's simplicity and unpretentious look, it's available everywhere, stays in sync both on desktop and mobile, the notes can contain any type of object including pictures and videos, and of course the search works great. There is even a dark colored scheme. I found out that rather than spend time making an organizational tree and filing things into separate buckets, simply placing everything in same place with an easy way of finding information works very fast and conveniently saves time.
I would say - give it a try..
