I recently read this:

No set of labels or algorithms solves anything once and for all; any working system for showing data to the user is a bag of optimizations and tradeoffs that are a lot worse than some Platonic ideal, but a lot better than nothing.

The article (Thanks due to Mr Gruber for the link) is really about the recent outrage at Amazon’s metadata and indexing system, which was followed by many using the hashtag #amazonfail. However, the section that really stood out to me was the above simple truth about indexing and searching systems I talked about in my first post.
