Sort array of objects with regex

I have question similar to this one JS array sort with regex but I have array of objects like this:

[  
   {  
      "applicationName":"APR",
      "homepage":"https://apr.apache.org/",
      "version":"1.5.2",
      "toolchain":"goolf-1.7.20",
      "description":"The Apache Portable Runtime (APR) is a supporting library for the Apache web server.\nIt provides a set of application programming interfaces (APIs) that map to the underlying Operating System (OS).

      "$$hashKey":"object:117"
   },
   {

   {

      "description":"Anaconda is a completely free Python 3 distribution (including for commercial use and redistribution). It includes more than 300 of the most popular Python packages for science, math, engineering, and data analysis."
   }
]

and I need to sort it based on regex taken from user and it should show first applications that start with the text provided by user then it should show application regex match description and toolchain, here is my code:

export default class CustomTabsShowController {

  static $inject = ['$stateParams', '$state', 'customTabRepository'];

  constructor($stateParams, $state, customTabRepository) {
    this.searchTerm = "";
    this.id = $stateParams.id;
    this.$state = $state;
    this.customTabRepository = customTabRepository;
  }
  getSortRank(obj) {
    var regex;
    var array = [obj.applicationName, obj.description, obj.toolchain];
    if (!this.searchTerm.match(/^\^/)) {
        regex = new RegExp('^' + this.searchTerm);
        for (var i = 0; i < array.length; i++) {
            if (regex.test(array[i])) {
                console.log(array[i] + ' ' + i);
                return i;
            }
        }
    }
    regex = new RegExp(this.searchTerm);
    for (var i = 0; i < array.length; i++) {
        if (regex.test(array[i])) {
            console.log(array[i] + ' ' + (i + 3));
            return i + 3;
        }
    }
    return array.length + 3;
  }
  search() {
    this.tableParams.filter({ $: this.searchTerm });
    this.customTabRepository.data.sort((a,b) => {
        return this.getSortRank(a) - this.getSortRank(b);
    });
  }
}

I'm sorting angular ng-table data but that should not be important. My code don't work as expected, it don't sort right, what wrong with my code?
