  search_this_q="cats";

    function load(){
        search(search_this_q)
        .then(function(data){
            console.log(data)
            return next_Page_Search(data.nextPageToken,search_this_q);
        })
        .then(function(data){

            return next_Page_Search(data.nextPageToken,search_this_q);

推荐答案

我有类似 Youtube 搜索方法的情况，我可以推荐使用 publishedAfter 和 publishedBefore 参数来缩短搜索时间.看起来 Youtube 试图通过估计来优化每个搜索请求的 CPU 服务器时间.因此，您需要更具体地使用您的搜索查询，或者您需要缩短搜索的时间范围.例如，我尝试了非常具体的视频，在描述中具有唯一编号.我可以在 Youtube 网站上轻松找到它，但如果不添加 publishedBefore 和 publishedAfter 大约 1 小时的发布时间，我无法使用 search 方法.所以，试试吧！

I have similar situation with Youtube search method and I can recommend to use publishedAfter and publishedBefore parameters to reduce timeframe for your search. Looks like Youtube trying to optimize cpu server time for every search request with estimates. So, you need to be more specific with your search query or you need to reduce timeframe for your search. For example I've experimented with very specific video with unique number in description. I can find it on Youtube website easily but I can't with search method without adding publishedBefore and publishedAfter about 1 hour of published time. So, try it!
