Rust documentation search bar bug

[xbonnetain]

The search bar in the documentation (on both https://doc.rust-lang.org/std/ and https://docs.rs) does not provide the results of a research if the searched word has been researched just before.

Steps to reproduce:

• In the search bar of https://doc.rust-lang.org/std, press a.
• Wait for the result page to appear.
• Press backspace.
• Wait for the original page to come back.
• Press a.
• The result page does not come back.

This has been observed on stable, beta and nightly, and works with any word, as long as it is written fast enough, and no intermediate search result are shown.
