Question

我正在尝试创建一个分析器，用空格替换特殊字符并将其转换为大写。然后，如果我想用小写搜索它也应该工作。

Mapping Analyzer：

s from the join table where:
  First subquery: 
        where there is not another join table row for that same category
        with an

通过用空格替换特殊字符来正确地标记单词。现在如果我从文本中搜索一个单词，它就不会检索到任何结果。

that is *not* in the set of

我没有从上面的GET查询中得到任何结果。得到如下结果：

s 
        for the category you are matching against, and
   Second subquery:
        where there is not an item in the category you are matching against
        that is not also in the category you are selecting (ci table)

任何人都可以帮助我！谢谢！

创建索引后，您似乎没有索引任何数据。对_analyze的调用不会对任何内容编制索引，只是简单地向您展示如何分析您发送给ES的内容。

首先，您需要通过指定使用您定义的分析器的映射来创建索引：

curl -XPUT 'http://localhost:9200/aida' -d '{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_analyzer": {
          "tokenizer": "standard",
          "char_filter": [
            "my_char_filter"
          ],
          "filter": [
            "uppercase"
            ]
        }
      },
      "char_filter": {
        "my_char_filter": {
          "type": "pattern_replace",
          "pattern": "(\\d+)-(?=\\d)",
          "replacement": "$1 "
        }
      }
    }
  },
  "mappings": {                        <--- add a mapping type...
    "doc": {
      "properties": {
        "text": {                      <--- ...with a field...
          "type": "string",
          "analyzer": "my_analyzer"    <--- ...using your analyzer
        }
      }
    }
  }
}'

然后你可以索引一个新的真实文档：

curl -XPOST 'http://localhost:9200/aida/doc' -d '{
   "text": "My name is Soun*arya?jwnne&yuuk"
}'

最后，您可以搜索：

curl -XGET 'http://localhost:9200/aida/_search' -d '{
  "query":{
    "match":{
      "text":"My"
    }
  }
}'

elasticsearch mapping analyzer - GET没有得到结果
