Is it true that parent/child concept slows down QPS?

Hi,

Is it true that parent/child concept slows down QPS (Query Per Second) count ?

Currently my Query looks something like this.

    {
  "query": {
    "filtered": {
      "query": {
        "bool": {
          "should": [
            {
              "query_string": {
                "fields": [
                  "Title.title^4",
                  "Title.ngrams_front^2",
                  "Title.ngrams_back"
                ],
                "defaultOperator": "or",
                "analyzer": "titles_default_analyzer",
                "query": "man"
              }
            },
            {
              "fuzzy": {
                "Title.title": {
                  "value": "man",
                  "boost": 1,
                  "min_similarity": 0.5,
                  "max_expansions": 20,
                  "prefix_length": 0
                }
              }
            }
          ]
        }
      },
      "filter": {
        "and": [
          {
            "terms": {
              "Tags": [
                "MUMBAI",
                "rall"
              ]
            }
          },
          {
            "terms": {
              "Status": [
                "NS",
                "CS"
              ]
            }
          }
        ]
      }
    }
  }
}

Why, are you having issues?

We wanted to try that, but not compromising the QPS count.
