elasticsearch - Elasticsearch 查询因query_string中的冒号而崩溃

Question

我在查询字词"query": "Schwarz AND People:"的末尾添加了一个冒号，这似乎破坏了查询。不知道为什么。这是 flex 搜索中的错误吗？我正在使用1.0.1。响应包含此令人困惑的异常。

: Encountered "<EOF>" at line 1, column 19. Was expecting one of: <BAREOPER> ... "(" ... "" ... <QUOTED> ... <TERM> ... <PREFIXTERM> ... <WILDTERM> ... <REGEXPTERM> ... "[" ... "{" ... <NUMBER> ... ]; nested: ParseException[Encountered "<EOF>" at line 1, column 19. Was expecting one of: <BAREOPER> ... "(" ...

下面是由于冒号而中断的查询。我需要冒号怎么办？

query_string中的冒号还用作字段和查询词之间的定界符，如here所示。

结果，它将其解析为无效查询。为了将冒号指定为查询词，您需要显式转义它。

范例:

{
  "query": {
    "filtered": {
      "query": {
        "bool": {
          "must": [
            {
              "query_string": {
                "fields": [
                  "name",
                  "message"
                ],
                "query": "Schwarz AND People\\:"
              }
            },
            {
              "range": {
                "created_time": {
                  "gte": 1363219771,
                  "lte": 1449623371
                }
              }
            }
          ]
        }
      }
    }
  },
  "size": 20,
  "sort": [
    {
      "total_interactions": {
        "order": "desc"
      }
    }
  ],
  "highlight": {
    "fields": {
      "name": {
        "pre_tags": [
          "<strong>"
        ],
        "post_tags": [
          "</strong>"
        ],
        "fragment_size": 500,
        "number_of_fragments": 1
      },
      "message": {
        "pre_tags": [
          "<strong>"
        ],
        "post_tags": [
          "</strong>"
        ],
        "fragment_size": 500,
        "number_of_fragments": 1
      }
    }
  }
}
