fuseJS 模糊搜索对我不起作用

Question

有没有 fuseJS 专家可以告诉我为什么 fuseJS 模糊搜索不适合我，我认为它应该。（请参阅下面的演示代码。）当我搜索 "presets" 时，我得到一个返回结果，即：

预设 ... eDirectory ... 2018/5/30 17:22:50 ... 4 KB

但是当我搜索 "sets" 时，我没有返回任何结果。我不应该为这两个搜索获得相同的结果吗？我需要在选项中添加一些东西吗？或者这种类型的搜索不能用 fuseJS 实现吗？

在此先感谢您能给我的任何帮助。

P.M.

Answer 1

看看threshold（摘自http://fusejs.io/）

Threshold

At what point does the match algorithm give up. A threshold of 0.0 requires a perfect match (of both letters and location), a threshold of 1.0 would match anything.

例如，

并将值更改为 0.2。然后你得到一个结果。

您可以尝试使用更多数据集为 threshold 设置一些不同的值并检查结果。

var files = [{ name: "zips", type: "bDirectory", dateModified: "2018/5/10 17:39:27", size: "1 KB" }, { name: "presets", type: "eDirectory", dateModified: "2018/5/30 17:22:50", size: "4 KB" }, { name: "workflow", type: "dDirectory", dateModified: "2018/6/11 7:23:11", size: "5 KB" }, { name: "software", type: "aDirectory", dateModified: "2018/6/14 14:35:36", size: "2 KB" }, { name: "nmm_data", type: "fDirectory", dateModified: "2018/6/14 15:37:08", size: "6 KB" }, { name: "jobs", type: "cDirectory", dateModified: "2018/6/15 13:43:47", size: "3 KB" }],
    searchString = "sets",
    options = { keys: ['name', 'type', "dateModified", "size"], threshold: 0.2, caseSensitive: false },
    f = new Fuse(files, options),
    output = f.search(searchString),
    i;

document.getElementById("searchString").innerHTML = searchString;
document.getElementById("json").value = JSON.stringify(files);
console.log(output);

for (i = 0; i < output.length; i++) {
    document.getElementById('results').innerHTML += output[i].name + ' ... ' + output[i].type + ' ... ' + output[i].dateModified + ' ... ' + output[i].size + '<br />'
}
