How to set up atlas search index with autocomplete for field inside an array?

[urosbrkic1_N_A]

Hi,

I have following structure of document

{
title : “some title”,
someData: [
{ itemNo: “1”, description: “dpcxed”},
{ itemNo: “2”, description: “edfic”},
]
}

how to setup atlas search index with autocomplete, for each description in someData array?
And how to query it?

I’v read this post :

Hi , i created a new search index with below json config. { “mappings”: { “fields”: { “items”: { “dynamic”: false, “fields”: { “name”: { “type”: “autocomplete” } }, “type”: “embeddedDocuments” } } } } But when i try to execute . { index: ‘embedded’, autocomplete: { query: ‘dp’, path: ‘name’, tokenOrder: ‘sequential’, fuzzy: { // maxEdits: 1, // “maxExpansions”: 100, } …

and it is stated here, that the work on this feature is in progress?
Could you provide me working example with this setup?
And also how to query it.

Thanks in advance
