How I can search in the nested array of strings?

[vedmant]

Here is my data:

[
  [
    'test1',
    'test2',
    'test3-match',
  ],
  [
    'test11',
    'test12-match',
    'test13',
  ],
  [
    'test21',
    'test22',
    'test23',
  ],
]

How I can search this array? I need to return only subarrays that include any matches.

[hrushi2003]

function Search(array, searchItem){ for(let i = 0; i < array.length; i++){ for(let j = 0; j < array[i].length; j++){ if(array[i][j] === searchitem){ return array[i];}}} } I think it will help @vedmant

@hrushi2003 How and where I can use this code?

[hrushi2003]

@hrushi2003 So how to use it with Fuse.js?

I don't think fuse.js can understand the structure of your array as it is, but I was able to search it by transforming it first.

For example, given your array of arrays, of type string[][]:

[
  ["test1", "test2", "test3-match"],
  ["test11", "test12-match", "test13"],
  ["test21", "test22", "test23"],
];

You can map them first, to type { foo: string[] }[], e.g.:

[
  { foo: ["test1", "test2", "test3-match"] },
  { foo: ["test11", "test12-match", "test13"] },
  { foo: ["test21", "test22", "test23"] }
]

... and then feed that to fuse.js, like so:

// Your original list.
const list = [
  ["test1", "test2", "test3-match"],
  ["test11", "test12-match", "test13"],
  ["test21", "test22", "test23"],
];

// Map the list to a structure that `Fuse.js` can understand.
const mapped = list.map((x) => {
  return {
    foo: x,
  };
});

// Specify the `key` option, with the placeholder property name we want to search.
const options = {
  keys: ["foo"],
};

const fuse = new Fuse(mapped, options);

// Do the search..
return fuse.search("match");

The results would look like this:

[
  {
    "item": {
      "foo": ["test1", "test2", "test3-match"]
    },
    "refIndex": 0
  },
  {
    "item": {
      "foo": ["test11", "test12-match", "test13"]
    },
    "refIndex": 1
  }
]
