Search in Array<String> returns indexes instead of items

Hello, I used Live Demo page to check a search in flat array:

const list = [
  { value: "85626400800" },
  { value: "81323902061" },
  { value: "8079842032" },
  { value: "7825731309" },
  { value: "9492224473" },
  { value: "81323902062" },
  { value: "71509915863" },
  { value: "84718105204" },
  { value: "81323902013" },
  { value: "80487910890" },
]

var options = {
  shouldSort: true,
  tokenize: true,
  matchAllTokens: true,
  threshold: 0,
  location: 0,
  distance: 0,
  maxPatternLength: 32,
  minMatchCharLength: 1,
  keys: [
    "value"
  ]
};
var fuse = new Fuse(list, options); // "list" is the item array
var result = fuse.search("804");

/* SEARCH RESULTS */
[
  {
    "value": "80487910890"
  }
]

But when I try to search by flat list it returns indexes instead of items

const list =  [
  "85626400800",
  "81323902061",
  "8079842032",
  "7825731309",
  "9492224473",
  "81323902062",
  "71509915863",
  "84718105204",
  "81323902013",
  "80487910890",
]

// Options without a "key" property
var options = {
  shouldSort: true,
  tokenize: true,
  matchAllTokens: true,
  threshold: 0,
  location: 0,
  distance: 0,
  maxPatternLength: 32,
  minMatchCharLength: 1,
};
var fuse = new Fuse(list, options); // "list" is the item array
var result = fuse.search("804");

/* SEARCH RESULTS */
[
  9
]

Looks like issue is here — https://github.com/krisk/Fuse/blob/master/src/index.js#L136 Why is that?

It’s probably just a weird decision that was made a long time ago. Not so hard to get around:

// Fuse has a quirk where, when the input is an array of strings instead of
// objects, it only returns the index to each result. That means we need to
// re-map those indexes to the original list items after the search completes.
var result = fuse.search("804").map(i => list[i]);

I wonder if it’s possible to type correctly? Maybe with conditional types.

export interface FuseResult<T> {
    item: T extends string ? number : T;
    matches?: any;
    score?: number;
  }
