Searching for most common words in https://crates.io will usually return a lot of results, e.g. https://crates.io/search?q=foo. That's because of README.md being full text indexed.

I think it's useful to have README.md indexed but perhaps it could use some preprocessing such as dropping code blocks to reduce the amount of noise.
