* 获取二级搜索引擎id | |
* @param {Array} seInfo 某个搜索引擎的信息 | |
* @return {number} 二级搜索引擎id | |
* | |
* 匹配类型参数说明 | |
* 0:位置不固定,正则匹配,例如www.google.com/search?tbm=isch | |
* 可以用|分隔多个匹配项,例如谷歌新闻 | |
* 1:sub.domain.com形式,例如news.baidu.com | |
* 2:domain.com/sub形式,例如www.bing.com/images | |
* 符合1或2的尽量用1或2,都不符合的才用0,这样会更准确,减少误判 | |
