> Search Type: Sub String Exact Regular Expression

Google has an advantage in terms of index size, but definitely lose in terms of precision. The way it munges queries is a bit unsettling at times, and even the "exact" option doesn't seem to always work the way it should.

Have you tried verbatim mode? (Thanks https://news.ycombinator.com/item?id=12046056)

That is a huge improvement over the normal search, but unfortunately it's not truly verbatim. For example, searching for `self` with the backticks turns up results for just self with no backticks. It works with some symbols but not others, not sure why.
