Fuse.js : retrieve records which exactly match a multiple word search

Question

Using Fuse.js I'm trying to make a "multiple word" search in a JS object to get the records which contain exactly each word looked for.

My data structure is the following (from fuse.js):

[{
    title: "The Lost Symbol",
    author: {
      firstName: "Dan",
      lastName: "Brown"
    }
 }, ...]

My issue is that my setup works for a one word search (Brown for example) but not for more (Dan Brown or Dan Brown Vinci).

Fuse options:

{
    shouldSort: true,
    matchAllTokens: true,
    findAllMatches: true,
    includeScore: true,
    threshold: 0,
    location: 0,
    distance: 100,
    maxPatternLength: 32,
    minMatchCharLength: 1,
    keys: [
        "title",
        "author.firstName",
        "author.lastName"
    ]
}

new Vue({
    el: "#app",
    data: {
        Fuse: null,
        searchText: '',
        result : [],
        fuseOptions: {
            shouldSort: true,
            matchAllTokens: true,
            findAllMatches: true,
            includeScore: true,
            threshold: 0,
            location: 0,
            distance: 100,
            maxPatternLength: 32,
            minMatchCharLength: 1,
            keys: [
                "title",
                "author.firstName",
                "author.lastName"
            ]
        },
        list: [{
                title: "Old Man's War",
                author: {
                    firstName: "John",

Answer 1

Unfortunately, fuse.js does not look into all fields, rather one matching field. I solved this problem by putting all the fields into one field with array of strings.

Example:

[{
    title: "The Lost Symbol",
    author: {
      firstName: "Dan",
      lastName: "Brown"
    },
    keywords: ["The Lost Symbol", "Dan", "Brown"] //values of title, firstname & lastname
 }, ...]

And just specify keywords Fuse option's keys field

{
    shouldSort: true,
    matchAllTokens: true,
    findAllMatches: true,
    includeScore: true,
    threshold: 0,
    location: 0,
    distance: 100,
    maxPatternLength: 32,
    minMatchCharLength: 1,
    keys: ["keywords"]  //just put keywords alone
}

This worked for me. Hope it works for you too.
