流星搜索清除结果

Question

我想让流星清除最后一个查询，它不积累我的研究成果。如果我在输入“NºPatrimónio”中搜索，然后在“CódigoInformática”中再次搜索，我想清除第一个查询结果。发生的事情是它汇集了第一个和第二个查询结果。总结一下，我想单独查询结果。 Meteor search page

if (Meteor.isClient) { 

    Template.pesquisar.helpers({ 
    pesquisaEquipamentos: function() { 
     return Equipamentos.find();

    Template.pesquisar.events({

尝试停止订阅，然后再次调用它：

var mySub; 
Template.pesquisar.events({ 
    "keypress input": function(event, template) { 
    if (event.keyCode == 13) { 
     var search = {}; 
     search.value = event.target.value 
     search.name = event.target.name 
     if (mySub) mySub.stop(); // if you've previously subscribed clear those results 
     mySub = Meteor.subscribe("pesquisaEquipamentos", search); 
     event.target.value = ''; 
    } 
    } 
});
