"""喜马拉雅搜索（对应 sdk/xm/musicSearch.ts，web 通道）。

接口: https://www.ximalaya.com/revision/search?core=track&kw=&page=&rows=&spellchecker=true&condition=relation&device=web
实测（2026-10-02）匿名可用（注意：同参数的 /revision/search/main 与 /search/main 会命中
risk invalid 风控，本端点 + condition=relation&device=web 不受影响）。

返回 data.result.response.docs[]，字段 id/title/duration(秒)/nickname/album_id/album_title/
