[SOLVED] Unable to add fulltext index to $id field

I've been trying to run a single query where I find multiple documents by a list of document ids. I found out you can find multiple documents by an array by using Query.search, if the attribute has an index with fulltext as type. So in order to find multiple documents I want to add a fulltext index on the $id field. When I try to add this index I get this error back:

{
    "message": "Invalid `key` param: Parameter must contain at most 36 chars. Valid chars are a-z, A-Z, 0-9, period, hyphen, and underscore. Can't start with a special char",
    "code": 400,
    "type": "general_argument_invalid",
    "version": "1.4.7"
}

Is it in any way possible to do query with an array as input?

first of all, if you want to filter by document ids, you don't need Query.search(). You can use Query.equal('$id', [id1, id2, id3]).

secondly, when you tried creating your index, what did you put as the key?

Ahh, now I feel stupid. But thank you, that works 😅 My input when creating the index was:

{
    "key":"$id",
    "type":"fulltext",
    "attributes":[],
    "orders":["ASC"]
}

ya, $id is now allowed for key. FYI, key is just a name for you. the important part in creating indexes is included the attributes in the attributes array

Ah, that makes sense. Thank you!
