Question

查询:

http://:9200 / rif_orig / rif / _search？q = F7Y *＆from = 0＆size = 10

响应:

{
  "took": 4,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 1,
    "max_score": 1.0,
    "hits": [
      {
        "_index": "rif_orig",
        "_type": "rif",
        "_id": "INF7YCOriginale",
        "_score": 1.0,
        "_source": {
          "IDRIF": "INF7YCOriginale",
          "R01PRO": "IN",
          "R01RIF": "F7YC",
          "R01DES": "CANDELA CHAMPION",
          "R01PRE": "3.20",
          "R01CPR": "",
          "ARTPRO": "IN",
          "ARTPAG": "1",
          "ALTORG": "Originale",
          "timestamp": "201407091018"
        }
      }
    ]
  }
}

查询:

http://:9200 / rif_orig / rif / _search？q = IN＆from = 0＆size = 10

响应:

{
  "took": 5,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 0,
    "max_score": null,
    "hits": [

    ]
  }
}

我尝试了q =“IN”，q = R01PRO:“IN”，q = R01PRO:(IN)q = R01PRO:“\” IN“\”相同的结果...。
“IN”是保留字吗？我该如何逃脱呢。
我正在使用Elastich Search 0.9，但无法立即升级...
谁能帮我？

您正在使用哪个版本的Elasticsearch？ “IN”是stop word，但是默认情况下，大于1.0的Elasticsearch版本不会删除停用词。您正在使用旧版本的Elasticsearch或已启用停用词删除功能。
