    "must": {
      "term": {
        "price": "2000"
      }
    }
  }
}

Basic example 2:

input: "price=2000 AND year=2021"

Output:

{
  "bool": {
    "must": [
      {
        "bool": {
          "must": {
            "term": {

              "bool": {
                "must": {

            {
              "bool": {
                "must": [
                  {
                    "bool": {
                      "must": {
                        "term": {
