我正在使用视频拾取器应用程序(由LockeVN: https://github.com/lockevn/YouTube-video-picker)，我得到的结果不像他们在youtube网站(或github上的任何其他搜索应用程序)上订购。
例如: 我输入:"奇异公司壮举安吉·布朗我要得到你"。我在youtube上找到的第一个视频是:"奇异公司的壮举安吉·布朗- I'm Gonna get You(1992)"。我在video Picker app中看到的第一个视频是:"BIZARRE INC - I' m GONNA get YOU (SAVERY)"。MILLER MASHUP MIX
注意:两者都被设置为orderby=relevance，当我改变max-results时，视频的顺序会改变;只有当max-result设置为1时，结果才会被正确排序。
有谁知道这是如何修复的吗?

我不确定，但我猜Youtube使用你的偏好来过滤视频搜索。
尝试其他类型的过滤器，看看你得到什么
