here is the code , the url is a visual host
I wonder why , when I shut down the wifi , the alfred will return the result more quickly?
If turn on the wifi,will be more slow, I have logged the url in alfy.fetch function,which shows
they both use the cached data .

alfy.fetch('http://linuxcmd.com/data.json',
           {maxAge: 86400000}).then(result => {
    var commands = [];
    var e = 0;
    for(var a in result){
      ++e;
      result[a]['id'] = e;
      commands.push(result[a]);
  }
  var i=0,
  page_size = commands.length,
  arrResult = [],
  query=alfy.input;
  if(commands&&commands.length&&toString.call(commands).indexOf('Array')>-1){
    var count = 0
    for (; i < page_size; i++) {
      if(isSreachIndexOF(commands[i].n,query)
       || isSreachIndexOF(commands[i].d,query) 
      ){
        if(count < page_size){
          arrResult.push(commands[i]);
          ++count;
        }
      }
    }
  }
  var items = [];
  for(var i = 0;i< arrResult.length;i++){
    items.push({
      title: arrResult[i].n,
      subtitle: arrResult[i].d,
      arg: arrResult[i].n
    })
  }

  if(items.length < 1){
    items.push({
      title: "没有搜素到内容",
      subtitle: "请尝试其它关键字",
    })
  }
  alfy.output(items);
});
