How should I resolve this error?

You need to put your query in the query part of the search request body. Try this:

GET my_index/my_type/_search
{
  "query": {
    "multi_match": {
      "query": "Quick brown fox",
      "type": "best_fields",
      "fields": [
        "title",
        "body"
      ],
      "tie_breaker": 0.3,
      "minimum_should_match": "30%"
    }
  }
}

Thankyou @colings86 for resolving the issue.
