JS - Search String with quotes as well as without quotes via regex

Question

I would like to be able to perform the following, using examples based on my code:

• Search for Carpenter Company returns 2 records
• Search for "Carpenter Company" (with the double quotation marks) returns 1 record

I couldn't get it to work so far, also tried to combine the regex with the following expression:

"[\w\s]+\"

Here is my plunker sample:

And specifically the code part I am looking into:

    var app = angular.module('filter', [])
app.controller('MainController', function($scope) {
  $scope.deals = [{
    lob: 'Marine, Motor, Carpenter',
    cedent: 'ABC Paris Company',
    treaty: 'QS - Test'
  }, {
    lob: 'Liability',
    cedent: 'Carpenter Company',
    treaty: 'W/XL Test'
  }];
});

// filterBy implementation
app.filter('filterBy', function() {
  return function(array, query) {
    var parts = query  && query.trim().split(/\s+/g) ,
      keys = Object.keys(array[0]);
    if (!parts || !parts.length) return array;
    return array.filter(function(obj) {
      return parts.every(function(part) {
        return keys.some(function(key) {
          return String(obj[key]).toLowerCase().indexOf(part.toLowerCase()) > -1;
        });
      });
    });
  };
});

Thank you in advance for some hints how to solve it.

You need to adjust the code a bit to collect the search keywords from the input:

app.filter('filterBy', function() {
  return function(array, query) {
    if (!query) return array;                    // Added for better error checking
    var parts = query  && get_query(query.trim()) , // Use the get_query function here
      keys = Object.keys(array[0]);
    if (!parts || !parts.length) return array;
    return array.filter(function(obj) {
      return parts.every(function(part) {
        return keys.some(function(key) {
          return String(obj[key]).toLowerCase().indexOf(part.toLowerCase()) > -1;
        });
      });
    });
  };
});

function get_query(qry) {      // Function to collect search keywords
  var re = /"([^"]+)"|\S+/g;   // The regex gets all "..." or
  var m;                       //  non-whitespace substrings
  var res = [];
  while ((m = re.exec(qry)) !== null) { 
    res.push(m[1] ? m[1] : m[0]);      // Get either the captured text inside ""
  }                                    // or a non-whitespace chunk
