[ ] 搜索关键词不能为空

Error message

[%s] 搜索关键词不能为空

What it means

Sentinel validation error in YulinshufaPlugin.searchImpl (plugin/yulinshufa/yulinshufa.go:137): the keyword is empty after trimming (and title_en fallback produced nothing usable), so the search is skipped before any request.

Solutions

1. Reject empty keywords at the entry point before invoking the plugin
2. Skip the plugin for blank inputs instead of erroring

When it happens

Trigger: Thrown at plugin/yulinshufa/yulinshufa.go:137 when the library encounters an invalid state.
