AngularJS filter for multiple strings

Question

I\'m working through the AngularJS tutorial, and understand the basics of

However, the out of the box implementation seems limited to just filter the list of items

Here's my version. It uses JonoWilko's method of using the built in filterFilter combined with surfbud's AND/OR flag (defaulted to "AND").

JavaScript

angular.module('filters').filter('searchFilter', function($filter) {

    return function(inputArray, searchText, booleanOp) {
        booleanOp = booleanOp || 'AND';

        var searchTerms = (searchText || '').toLowerCase().split(/\s+/);

        if (booleanOp === 'AND') {
            var result = inputArray;
            searchTerms.forEach(function(searchTerm) {
                result = $filter('filter')(result, searchTerm);
            });

        } else {
            var result = [];
            searchTerms.forEach(function(searchTerm) {
                result = result.concat($filter('filter')(inputArray, searchTerm));
            });
        }

        return result;
    };
});

CoffeeScript

angular.module('filters').filter 'searchFilter', ($filter)->

    (inputArray, searchText='', booleanOp = 'AND')->
        searchTerms = searchText.toLowerCase().split(/\s+/)

        if booleanOp is 'AND'
            result = inputArray
            searchTerms.forEach (word)->
                result = $filter('filter')(result, word)

        else
            result = []
            searchTerms.forEach (word)->
                result = result.concat $filter('filter')(inputArray, word)

        result

'AND' Usage (default)

'OR' Usage
