Allow autocomplete search on multiple fields using a wildcard path or by specifying multiple fields in the path

Currently, (unlike the text operator) the autocomplete operator does not accept a path which is an array of field names. Also, a wildcard path ("path": {"wildcard": "*"}) cannot be specified for an autocomplete query. Therefore, the only way to perform an autocomplete search on multiple fields is by using the compound operator.

This is a feature request to allow autocomplete search on multiple fields by using a wildcard path or by accepting an array of multiple fields in the path.

    Could we maybe get a little bit of visibility on that? Are we looking at a few weeks? a few months? one more year?
    Any vague info would help us out there planning our developments.

    Thanks.

    Hi there. Could we at least get an update as it is nearly a year since work was going to begin on this. Thanks in advance.

    Any update on that? It's still quite blocking not to be able to do a simple autocomplete search on an array of objects.

    Thanks, please keep us posted.

    Also would love this. I can work around for now, but would be a nice feature. Any updates?

    Would also be great if this limitation could be mentioned in the docs. If it is already, I didn't see it. Thanks.

    Any update on this issue? I see the last comment was about 6 months ago. Running into this one now.

    I ran a test that worked:

    {
    "mappings": {
    "dynamic": false,
    "fields": {
    "category": {
    "foldDiacritics": true,
    "maxGrams": 15,
    "minGrams": 2,
    "tokenization": "nGram",
    "type": "autocomplete"
    },
    "wisdom": {
    "foldDiacritics": true,
    "maxGrams": 15,
    "minGrams": 2,
    "tokenization": "nGram",
    "type": "autocomplete"
    }
    }
    }
    }

    Search with:

    db.examplecoll.aggregate([
    {
    $search: {
    "compound": {
    "should": [
    {
    "autocomplete": {
    "query": "conn sur",
    "path": "category"
    }
    },
    {
    "autocomplete": {
    "query": "conn sur",
    "path": "wisdom"
    }
    }],
    "minimumShouldMatch": 1
    }
    }
    }
    ])

    This feature will be useful. We have lot of use case for multiple fields and partial search with case insensitive.
