ElasticSearch - [parsing_exception] [multi_match] некорректный запрос

Question

Я получаю эту ошибку [parsing_exception] [multi_match] искаженный запрос в то время как массовый поиск в базе данных ElasticSearch. Я не нашел ошибок на объекте JSON. запрос на is_processed ": false Записи, содержащие name1 это поля [" NAME "," NICKNAME "] или Записи, содержащие name2 это поля [" NAME "," NICKNAME "]

условие: is_processed ": false И (name1 ИЛИ name2 в [" NAME "," NICKNAME "])

import * as elasticsearch from "elasticsearch";

const elasticClient = new elasticsearch.Client({
    host: process.env.ELASTIC_HOST,
    log: 'error'
})

elasticClient.msearch({
            index: indexName,
            type: docType,
            body: payload
        })

I отправляю эту полезную нагрузку для поиска

payload = '
           {}
           {
            "query": {
                      "bool": {
                               "must": [
