An awful lot of products _would_ lend themselves to filtering, but the folks putting the sites together don't bother coming up with good parameters, or when they do, they don't populate them on all the relevant products.

This vexes me constantly on HomeDepot.com, for instance. I was looking for a set of sockets, either 1/4" or 3/8" drive, metric 6-point, deep, impact. I was shopping for sockets at the Depot because I was already buying some other things, and I honestly like Milwaukee's offerings in this space, so let's take a look.

Search for "metric deep socket", so far so good. Gets me into the category so parametric filters appear. Filter by "6-point" and all the sets disappear -- that parameter only applies to sockets sold individually, despite most sets consisting exclusively of 6-point or 12-point, rarely a mix, and they even indicate this in their item titles. The data is there, but you can't filter by it, because the site sucks.

Just the first example to mind because it happened two days ago.
