Finding in MongoDB using two keys with Express JS and Node

I need help. I’m using the command .find() in my web application (express JS and Node) but it doesn’t work. I want to search with multiple words.

It’s quite confusing because when I use the command $all, and I force two words (for exemple, salt or sugar), it works, but when I’m using variables it doesn’t…

I’m attaching some images (the route itself and the function with its fetch):

Here the route

Here the function with its fetch

Many thanks

    You have passed ingredientBucar1 and ingredientBucar2 with + sign

    it will become a single string.
    so You are passing ‘sa1’ and ‘azucar’ in ingredientBucar1 and ingredientBucar2, It will be passed to api as ‘sa1’ and ‘azucar’

    To overcome this You can pass it in post api and get in req.body
    or you can pass it through search params or pass them through 2 different query params like

    your_api_endpoint/:ingredientBucar1/:ingredientBucar2

    It’s me, here is the code:

    FUNCIONES.JS
    function buscarPorIngredientes(){

    // let ingredienteABuscar01=document.getElementById("buscarIngrediente01","buscarIngrediente02","buscarIngrediente03","buscarIngrediente04","buscarIngrediente05").value;

let ingredienteABuscar1=document.getElementById("buscarIngrediente01").value;
let ingredienteABuscar2=document.getElementById("buscarIngrediente02").value;

fetch("/busquedaIngredientes/"+ingredienteABuscar1+ingredienteABuscar2
    
)
  .then(function(res){

    return res.json();

},
)

.then(function(datos){

    for (let i = 0; i < datos.length; i++){

    document.getElementById("divBuscarPorIngrediente").innerHTML+=
    `<div>
    <h4>${datos[i].nombre}</h4>
    <p>INGREDIENTES: ${datos[i].ingredientes}</p>
    <img src="${datos[i].imagen}" width="300"></a></p>
    </div>`;
    }
},
);

    };

    INDEX.JS

    `app.get("/busquedaIngredientes/:ingredientes",buscarPorIngredientes2);
    function buscarPorIngredientes2(req,res){

    const ingredienteABuscar1=req.params.ingredientes;
const ingredienteABuscar2=req.params.ingredientes;

app.locals.db.collection("cocteles").find({ingredientes: {$all: [

    // ingredienteABuscar1,
    // ingredienteABuscar2

    "sal",
    "azucar"

]}},
    
    console.log(ingredienteABuscar2),
    
)

.toArray(
    function(err,datos){

        if(err!=null){

            console.log(err);
            
        }
        
        else{

            console.log(datos);
            res.send(datos);

        }
    }
)

    };`
