## wildcard query

```auto
GET information/_validate/query?explain
{
  "query": {
    "bool": {
      "should": [
        {
          "wildcard": {
            "title": "cve-2018*"
          }
        },
        {
          "wildcard": {
            "content": "cve-2018*"
          }
        }
      ]
    }
  }
}

```

the explain result of `wildcard` query

```auto

{
  "valid": true,
  "_shards": {
    "total": 12,
    "successful": 12,
    "failed": 0
  },
  "explanations": [
    {
      "index": "manual_infos",
      "valid": true,
      "explanation": "title:cve-2018* content:cve-2018*"
    },
    {
      "index": "twitter-com",
      "valid": true,
      "explanation": "title:cve-2018* content:cve-2018*"
    }
  ]
}

```

## match\_phrase\_prefix query

```auto
GET information/_validate/query?explain
{
  "query": {
    "bool": {
      "should": [
        {
          "match_phrase_prefix": {
            "title": {
              "query": "cve-2018"
            }
          }
        },
        {
          "match_phrase_prefix": {
            "content": {
              "query": "cve-2018"
            }
          }
        }
      ]
    }
  }
}

```

the explain result of `match_phrase_prefix` query , and the result is a malformed json

```auto
{
  "valid": true,
  "_shards": {
    "total": 12,
    "successful": 12,
    "failed": 0
  },
  "explanations": [
    {
      "index": "manual_infos",
      "valid": true,
      "explanation": """title:"cve-2018*" content:"cve-2018*""""
    },
    {
      "index": "twitter-com",
      "valid": true,
      "explanation": """title:"cve-2018*" content:"cve-2018*""""
    }
  ]
}

```
