var collection=[
  {
    "DSP_MAQ": "Máquina 4",
    "VAL": "CPP@4@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 5",
    "VAL": "CMIP@5@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 6",
    "VAL": "CMIP@6@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 7",
    "VAL": "CMIP@7@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 8",
    "VAL": "CPP@8@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 9",
    "VAL": "CMIP@9@1900-01-01"
  },
  {
    "DSP_MAQ": "Máquina 10",
    "VAL": "CMIP@10@1900-01-01"
  }
 
];
 var search='CPP@';
    var results=_.filter(collection,function(item){
    return item.VAL.indexOf(search)>-1;
    });
    console.log(results);

 var search='CPP@';
    var results=_.filter(collection,function(item){
    return item.VAL.indexOf(search)>-1;
    });
    console.log(results);

回答2:

var results = _.filter(collection,function(obj) {
    return obj.VAL.indexOf(search) !== -1;
});

 var search='CMIP@9@1900-01-01';
var filterList = collection.filter(function(item) {
 return item.VAL === search;
})
console.log(filterList)
