I think that "for writing" is incredibly generic and a terrible search term. If you were talking to a human being about this, and you clarified that you weren't simply looking for text editors, but text editors "for writing", I would tell you that you hadn't clarified anything at all. Do you think one doesn't "write code"?

You might as well had said "for typing". And even THAT might have implied voice vs keyboard.

The (reasonable—IMO) expectation here is that search engines should be smart enough to understand queries like that. Even Google used to be better at that, until they succumbed to other priorities.
