query is empty

Error message

query is empty

What it means

Input validation at the top of BaiduProvider.Search: normalizeBaiduQuery (which enforces the Baidu AI Search API's query constraints) reduced the input to an empty string — the raw query was empty or contained only characters the API forbids. The search is aborted before any request is built.
