无法从首页提取search2参数

Error message

无法从首页提取search2参数

What it means

Extraction sentinel in u3c3 getSearch2Parameter: a mirror's homepage was fetched (HTTP 200, body read fine) but extractSearch2FromHTML found no search2 value in the HTML. Set as lastErr and the loop moves to the next domain; fatal only when all domains fail. Indicates the page template or obfuscation changed, or a challenge page was served.

Solutions

1. Update the extraction regex/logic for the new homepage structure
2. Verify the served page isn't a captcha/block page
3. Add new mirror domains to try
