Question

在下面的示例中，它已在es 2.3和1.7上调用。

刚开始我安装了插件：https://www.elastic.co/guide/en/elasticsearch/plugins/current/analysis-stempel.html#analysis-stempel

接下来我的步骤是检查正确安装的插件：结果在我的屏幕上：

Installed plugins in /home/adam/Desktop/elasticsearch-2.3.0/plugins:
- analysis-stempel
- marvel-agent
- license

接下来我添加了博客的映射：

curl -XPUT localhost:9200/my_index -d '{ 
 "mappings": {
    "blog": {
      "properties": {
        "title": { 
          "type": "string",
          "fields": {
            "polish": { 
              "type":     "string",
              "analyzer": "polish"
            }
          }
        }
      }
    }
  }
}
'

然后我添加了文件：

curl -XPUT localhost:9200/my_index/blog/1 -d
'{ "title": "Bardzo kocham zółwie"}'

我用的时候：

curl -XGET localhost:9200/_search -d
'{
  "query": {
    "multi_match": {
      "type":     "most_fields", 
      "query":    "zółwie",
      "fields": [ "title", "title.polish" ]
    }
  }
}
'

Elasticsearch返回正确的结果但是如果我把：

curl -XGET localhost:9200/_search -d
'{
  "query": {
    "multi_match": {
      "type":     "most_fields", 
      "query":    "zolwie",
      "fields": [ "title", "title.polish" ]
    }
  }
}'

Elasticsearch没有任何回报。

问题在于抛光特殊字符。

第二个查询所需的是asciifolding token filter。我建议使用以下映射，以涵盖更多用例：

{
  "settings": {
    "analysis": {
      "analyzer": {
        "folding": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "asciifolding"
          ]
        }
      }
    }
  },
  "mappings": {
    "blog": {
      "properties": {
        "title": {
          "type": "string",
          "fields": {
            "folding": {
              "type": "string",
              "analyzer": "folding"
            },
            "polish": {
              "type": "string",
              "analyzer": "polish"
            }
          }
        }
      }
    }
  }
}

这个查询：

{
  "query": {
    "multi_match": {
      "type": "most_fields",
      "query": "zolwie",
      "fields": [
        "title.*"
      ]
    }
  }
}

Stempel Polish Analysis Plugin作为Elasticsearch的插件并不起作用
