JavaScript fuzzy search

Question

I\'m working on this filtering thing where I have about 50-100 list items. And each items have markup like this:

Answer 1

I wasn't satisfied with list.js, so I created my own. This is probably not exactly fuzzy search, but I don't know what to call it. I simply wanted it to match a query without regard to the order of my words in the query.

Consider the following scenario:

• a collection of articles in memory exists
• order of query words appearance doesn't matter (e.g. "hello world" vs "world hello")
• The code should be easily readable

Here is an example:

var articles = [{
  title: '2014 Javascript MVC Frameworks Comparison',
  author: 'Guybrush Treepwood'
}, {
  title: 'Javascript in the year 2014',
  author: 'Herman Toothrot'
},
{
  title: 'Javascript in the year 2013',
  author: 'Rapp Scallion'
}];

var fuzzy = function(items, key) {
  // Returns a method that you can use to create your own reusable fuzzy search.

  return function(query) {
    var words  = query.toLowerCase().split(' ');

    return items.filter(function(item) {
      var normalizedTerm = item[key].toLowerCase();

      return words.every(function(word) {
        return (normalizedTerm.indexOf(word) > -1);
      });
    });
  };
};


var searchByTitle = fuzzy(articles, 'title');

searchByTitle('javascript 2014') // returns the 1st and 2nd items

Well, I hope this helps someone out there.
