Have u seen Mac OS X's search tokens?
The Finder includes tokens—a smart way to filter your searches. When you select a suggestion, a token is created. Instantly your search is filtered, and you see only the files that meet those criteria. You can change the scope of the token by clicking the arrow. If you want to narrow your search even more, you can use multiple tokens together. Search for specific file types: For example, if you wanted to find all the JPEG (.jpg) images on your Mac, type .jpg in the search field, and you'll immediately see results pop into the window. Click This Mac in the header to find all JPEGs on your entire hard disk. Not only will Spotlight display thumbnails, small images, of your JPEG images, it'll also list other things that match your criteria, such as documents that contain the word ”.jpg” in them. You can then access the file right from that Finder window.
I was wondering whether having a search-token "Around" that would filter numeric based searches to a +/-10% (or any other %) would make sense to include in a search field.
The problem that I have is that the fields that I want to search might be very precise, let's say $55402.12, $35014.16, $50957.78, and instead of using a range search token (that I'd assume would be complex to implement) that searches between $50000 and $56000 I'd like to search values around $53000 with a +/-10% tolerance.
So, in a nutshell the question is if having an "Around" Search Token would be useful of having usual ">" "<" ">=" "<=" ranges.
