vue3 嵌套搜索过滤器

Question

请帮助根据相似度输入搜索与关键字'info'：数组的比较返回filteredList()。

它总是说它未定义。

export default {
  data() {
    return {
      search: "",
      postList: [
        {
          title: "hello",
          info: ["one", "two", "three", "four"],
        },
        {
          title: "goodbye",
          info: ["five", "six"],
        },
      ],
    };
  },
  computed: {
    filteredList() {
      return this.postList.filter((item) => {
        return item.info.includes(this.search);
      });
    },
  },
};
</script>
