please take your time to properly format your snippets. This is super hard to read.

Also, please mention what error messages are being returned when you try to add highlighting, this is super useful for debugging.

Also, have you tried to run that query in the kibana console (not in your programming language) just to see if it works in principle? That's usually a good start before trying to do this in any programming language.

Hi, sorry if I'm not precise in what they ask me I'm new on elasticsearch.
The following is the code in node.js which it uses to create snippets. As you notice index = null.
Thank you

Fabio

Client.index({
index: "null",
//id: '1',
//type: 'constituencies',

      body: {
        "name": String(req.body.name),
        "surname": String(req.body.surname),
        "imageAccount": imageAccount1,
        //'String(req.body.imageAccount),

        "dateToDay": dataForm,
        "userid": arrayUser, //ho tolto le quadre
        // "userid": [String(list1)],

        "useridPadre": String(req.user.id),
        "title": String(req.body.title),
        "content": String(req.body.contenuto),
        //  "allBody": (String(req.body.title) +
        //    ' ' + String(req.body.content)),
        "show": false,
        "idGruppo": req.body.ddlGroup,
        "groupName": nota.nomeGruppo,
        "nome": String(nomeUt),
        "cognome": String(cognomeUt),
        "publicationState": req.body.DDLpublicationState

      }

I'm sorry, but this is not a fully reproducible example. See https://www.elastic.co/help
