As I researched the Search Filter Host problems plaguing my Surface Pro 3 — which results in hot temperatures and low battery life — I am reminded that functionality isn’t the same thing as usability.
The search index is a good idea. Windows builds an index of your files as unobtrusively it can, so when you search for something, results instantly appear. It’s a wonderful thing when it works. This is an example of high functionality; all modern operating systems should have it.
However, Microsoft’s implementation comes at a sacrifice to usability. While you can specify which locations and file types to include in the index, Windows will try to index everything within those specifications. Good, right? Nope.
