Definitely not for all cases, but in some cases yes. Where it really makes a difference is when you're looking for qualitative attributes of the webpage, rather than what words show up in it (e.g. “written by a woman", "is likely to convince someone who supports Trump", "talks about X/Y/Z but not A/B.”) It reads the actual content, so you can get oddly niche in a way you just can’t with keywords alone.

It might be worth putting those examples and other use cases you've found in the post. That is certainly something Google can't do.
