Fuse.js's example code doesn't return any result

Here is the example code of Fuse.js:

import Fuse from "https://deno.land/x/fuse/dist/fuse.esm.js";

const list = [
    {
      "title": "Old Man's War",
      "author": "John Scalzi",
      "tags": ["fiction"]
    },
    {
      "title": "The Lock Artist",
      "author": "Steve",
      "tags": ["thriller"]
    }
]

const options = {
    includeScore: true
}

const fuse = new Fuse(list, options)
const result = fuse.search('od man')

console.log("🚀 ~ fuse:", fuse)
console.log("🚀 ~ result:", result)

The result is just []. Do you know why is that?

>Solution :

You’ve not configured the keys:

const options = {
  includeScore: true,
  keys: ['title', 'author'],
};

will give you result:

[
  {
    item: { title: "Old Man's War", author: 'John Scalzi', tags: [Array] },
    refIndex: 0,
    score: 0.3556368284111493
  }
]
