/********************************
Google搜索人机验证解决方案
搜索内容时遇到人机验证立即并发使用多个代理策略、策略组尝试搜索内容，并返回最优结果。

脚本作者：@NobyDa
更新时间：2024/05/19
平台兼容：Surge(iOS4.9.3+/macOS4.2.3+) / QuantumultX(1.0.26+) / Loon(3.1.9[694]+)

可在 BoxJs(低优先级)、Surge模块参数、Loon插件参数中填写筛选的代理策略、策略组的正则表达式。
所有代理策略、策略组至多筛选、使用20个，可在BoxJs中测试匹配的策略，不筛选则表示随机使用。

注意：Surge由于策略架构问题，正则表达式筛选的"代理策略"不包含"外部代理策略"；
QuantumultX、Loon则无此限制，正则表达式可筛选所有"策略组"内的"代理策略"。
