Failed to parse query using Elastic Search API

I am using POST /_search API to search data in elastic search 5.6.0.

When I tried to search for query Android 8.0 (Oreo) search API worked successfully, but when I tried for Android 8.0 (Oreo elastic search failed with error Failed to parse query [Android 8.0 (Oreo]
Please have a look at error below:

{
  "shard":0,
  "index":"my_index",
  "node":"-Dzw5527SZGf7U0Ebut0PQ",
  "reason":{
    "type":"query_shard_exception",
    "reason":"Failed to parse query [Android 8.0 (Oreo]",
    "index_uuid":"wo7ihAX8Syy15MSDrS-Wsw",
    "index":"my_index",
    "caused_by":{
      "type":"parse_exception",
      "reason":"Cannot parse 'Android 8.0 (Oreo': Encountered \"<EOF>\" at line 1, column 17.\r\nWas expecting one of:\r\n    <AND> ...\r\n    <OR> ...\r\n    <NOT> ...\r\n    \"+\" ...\r\n    \"-\" ...\r\n    <BAREOPER> ...\r\n    \"(\" ...\r\n    \")\" ...\r\n    \"*\" ...\r\n    \"^\" ...\r\n    <QUOTED> ...\r\n    <TERM> ...\r\n    <FUZZY_SLOP> ...\r\n    <PREFIXTERM> ...\r\n    <WILDTERM> ...\r\n    <REGEXPTERM> ...\r\n    \"[\" ...\r\n    \"{\" ...\r\n    <NUMBER> ...\r\n    ",
      "caused_by":{
        "type":"parse_exception",
        "reason":"Encountered \"<EOF>\" at line 1, column 17.\r\nWas expecting one of:\r\n    <AND> ...\r\n    <OR> ...\r\n    <NOT> ...\r\n    \"+\" ...\r\n    \"-\" ...\r\n    <BAREOPER> ...\r\n    \"(\" ...\r\n    \")\" ...\r\n    \"*\" ...\r\n    \"^\" ...\r\n    <QUOTED> ...\r\n    <TERM> ...\r\n    <FUZZY_SLOP> ...\r\n    <PREFIXTERM> ...\r\n    <WILDTERM> ...\r\n    <REGEXPTERM> ...\r\n    \"[\" ...\r\n    \"{\" ...\r\n    <NUMBER> ...\r\n    "
      }
    }
  }
}

Below query worked for me :

{
  "query":{
    "bool":{
      "must":[
        {
          "query_string":{
            "query":"Android 8.0 (Oreo)",
            "default_operator":"AND"
          }
        }
      ]
    }
  }
}

Below query throws an exception:

{
  "query":{
    "bool":{
      "must":[
        {
          "query_string":{
            "query":"Android 8.0 (Oreo",
            "default_operator":"AND"
          }
        }
      ]
    }
  }
}

could you please help me on this, why am I getting an error when I missed ) in a query?

The parenthesis is a reserved character in the query string syntax, so you need to escape it like this

{
  "query":{
    "bool":{
      "must":[
        {
          "query_string":{
            "query":"Android 8.0 \\(Oreo",
            "default_operator":"AND"
          }
        }
      ]
    }
  }
}
