On June 13, 2019 at 12:52 p.m. PDT, a code change introduced an error, which caused language settings to default to English when using search modifiers. As a result, search results containing non-English modifiers were inaccurate.
We launched an investigation and resolved the issue on June 13, 2019 at 5:18 p.m. PDT.
