fuseJS fuzzy search is not working for me

Are there any fuseJS experts out there who can tell me why fuseJS fuzzy search is not working for me as I think it should. (Please see the demo code below.) When I do a search for "presets" I get one result returned, which is:

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

But when I so a search for "sets" I get no results retuned. Shouldn't I be getting the same results for both of these searches? Do I need to add something to the options? Or is this type of search not possible with fuseJS?

Thanks in advance for any help that you can give me.

P.M.

Solution

  • Just have a look to threshold (taken from 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.

    and change the value to 0.2, for example. Then you get a result.

    You may try with a greater set of data some different values for threshold and check the results.

    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 />'
