我想在 elasticsearch 中对 url 使用通配符查询。我正在使用弹性搜索 2.3.0

Question

我的索引是这样的：

GET pibtest1/_search

{
  "took": 5,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 11,
    "max_score": 1,
    "hits": [
      {
        "_index": "pibtest1",
        "_type": "SearchTech",
        "_id": "_update",
        "_score": 1,
        "_source": {
          "script": "ctx._source.remove(\"wiki_collection\")"
        }
      },
      {
        "_index": "pibtest1",
        "_type": "SearchTech",
        "_id": "http://www.searchtechnologies.com/bundles/jquery?v=gOdOgfykTFJnypePAvGweyMPwl-krhx8ntIhefPKelg1",
        "_score": 1,
        "_source": {
          "extension": {
            "X-Parsed-By": "org.apache.tika.parser.DefaultParser",
            "Content-Encoding": "ISO-8859-1",
            "resourceName": "http://www.searchtechnologies.com/bundles/jquery?v=gOdOgfykTFJnypePAvGweyMPwl-krhx8ntIhefPKelg1"
          },
          "keywords": "keywords-NOT-PROVIDED",
          "default_collection": true,
          "wiki_collection": false,
          "description": "description-NOT-PROVIDED",
          "connectorSpecific": {
            "discoveredBy": "http://www.searchtechnologies.com/",
            "xslt": "false",
            "pathFromSeed": "E",
            "md5": "OKTGVLEWTE5V4PWXUBM2RK3KMQ"
          },
          "title": "Title-NOT-PROVIDED",
          "url": "http://www.searchtechnologies.com/bundles/jquery?v=gOdOgfykTFJnypePAvGweyMPwl-krhx8ntIhefPKelg1",
          "remove": "wiki_collection",
          "UD": "http://www.searchtechnologies.com/bundles/jquery?v=gOdOgfykTFJnypePAvGweyMPwl-krhx8ntIhefPKelg1",

现在我想使用通配符查询来搜索一些 url 其中包含一些模式（例如 http://www.searchtechnologies.com/bundles）

这是我的通配符查询：

GET pibtest1/_search

    {
      "query": {
        "wildcard": {
          "url": {
            "value": "http://www.searchtechnologies.com/bundles*"
          }
        }
      }
    }

我正在使用匹配任何字符序列的“*”通配符。但我没有得到任何结果。我的输出如下所示：

{
  "took": 11,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 0,
    "max_score": null,
    "hits": []
  }
}

我希望我的结果包含那些 url 匹配此“http://www.searchtechnologies.com/bundles”模式的结果。任何帮助将不胜感激。

Answer 1

根据评论，您的 url 字段是经过分析的字段。因此，当您插入数据时，数据将被标记为 ["www.searchtechnologies.com", "v", "jquery", "gOdOgfykTFJnypePAvGweyMPwl", ...]。所以你的查询不会匹配这个字段。

您应该删除您的索引。
插入映射并指定 url 字段未分析 {"index":"not_analyzed"}
插入您的数据。
运行通配符查询。
