I want pure keywords-based search engine back [1]. If the keywords verbatim are not there, give me zero results back. It will be less time consuming to refine my query, or conclude that the stuff I am looking for is just not there. It's much better than sifting through low-precision results.

Google has 'verbatim' mode as such, which used to work well. I can't figure what they are doing to it, and why.
