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

update from 2022

You don't even need lodash now:

collection.filter(o => o.VAL.includes(search));

We now may use .filter method for arrays and .includes for arrays and strings. And arrow functions, of course!

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",

    "DSP_MAQ": "Máquina 10",
    "VAL": "CMIP@10@1900-01-01"

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