Question

我正在使用Elasticsearch

{
  "name" : "Angela Cairn",
  "cluster_name" : "prod-elastic",
  "cluster_uuid" : "iKkcI5FwTsGMtXacl3Qg-g",
  "version" : {
    "number" : "2.4.4",
    "build_hash" : "fcbb46dfd45562a9cf00c604b30849a6dec6b017",
    "build_timestamp" : "2017-01-03T11:33:16Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.2"
  },
  "tagline" : "You Know, for Search"
}

有时我发现下面的错误，而我找不到原因发生的原因以及解决方案

Answer 1

提供了主要线索:

QueryParsingException[Failed to parse]; nested: JsonParseException[Unexpected character ('t' (code 116)): was expecting comma to separate Object entries

ElasticSearch告诉您您要执行的查询是无效的JSON文档。

所述查询是这样的:

{ 
  "bool": { 
    "must_not" : [
      { "match":{ "status":"Inactive"} } ,
      { "match":{ "status":"Pending"} }
    ],
    "must": [
      { "match": { "location": "Delhi" } },
      { "bool": {
        "should": [
        { 
          "multi_match" : { 
            "query": "thionaid \\\\\\\\\\\\\\\\\",
            "type": "best_fields",
            "fields": [ "name^5", "brand^3" ],
            "boost":1,
            "fuzziness" : "AUTO",
            "prefix_length": 2
          }
        },
        { 
          "multi_match" : { 
            "query": "thionaid \\\\\\\\\\\\\\\\\",
            "type": "phrase_prefix",
            "fields": [ "name^5", "brand^3" ],
            "boost": 3
          }
        },
        { 
          "multi_match" : { 
            "query": "thionaid \\\\\\\\\\\\\\\\\",
            "type": "phrase_prefix",
            "fields": [ "sku" ],
            "boost": 5
          }
        }
      ]
    }
  }
  ]
 }
}

问题是这些字符串: "thionaid \\\\\\\\\\\\\\\\\"(一个太多的反斜杠)
