Searching string terms within arrays

[Joao_D_Junior (João D Junior)]

I am trying to search for a particular element within an array through a term, but when querying, I get nothing p.s: I am using elasticsearch 7.x.

I created the following query:

POST spring/_search
{
  "query": {
    "nested": {
      "path": "paragrafos",
      "score_mode": "avg",
      "query": {
        "bool": {
          "must": {
            "match": {
              "paragrafos.conteudo": """4 | Chapter 1: Terms\r?\n"""
            }
          }
        }
      }
    }
  }
}

my mapping is:

PUT spring/
{
  "mappings": {
    "properties": {
      "downloadUrl": {
        "type": "text",
        "fielddata": true,
        "fields": {
          "keyword": {
            "type": "keyword",
            "ignore_above": 256
          }
        }
      },
      "nome": {
        "type": "text",
        "fielddata": true,
        "fields": {
          "keyword": {
            "type": "keyword",
            "ignore_above": 256
          }
        }
      },
      "paginas": {
        "type": "nested",
        "properties": {
          "numeroPagina": {
            "type": "long"
          },
          "paragrafos": {
            "type": "long"
          }
        }
      },
      "paragrafos": {
        "type": "nested",
        "properties": {
          "conteudo": {
            "type": "text",
            "fielddata": true,
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "paginaNumero": {
            "type": "long"
          }
        }
      }
    }
  }
}

and my data is:

"id" : null,
"nome" : "BigData",
"downloadUrl" : "https://jdjscm.s3-us-west-2.amazonaws.com/teste/LEITE%2C+Carlos+Henrique+Bezerra.+Curso+de+Direito+Processual+do+Trabalho+(2015).pdf",
"paginas": [],
"paragrafos": [{"conteudo":"data", "paginaNumero": 5}, {"conteudo":"test", "paginaNumero": 6}, {"conteudo":"view", "paginaNumero": 7}

{
  "took" : 0,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 0,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  }
}

Is there an error in my query?

Is there an error in my query?

I've tested with filtered and filter, but returns all unfiltered objects;
