use python library for custom filter analyzer in elasticsearch

问题

我想为波斯语文本创建一个“index”，并为其创建词干处理器。以下是如何将“PersianStemmer” Python库实现到Elasticsearch的“analyzer”中的示例：

  1. PUT my_index
  2. {
  3.     "settings": {
  4.         "analysis": {
  5.             "filter": {
  6.                 "persian_stemmer": {
  7.                     "type": "stemmer",
  8.                     "name": "persian"
  9.                 }
  10.             },
  11.             "analyzer": {
  12.                 "persian_analyzer": {
  13.                     "type": "custom",
  14.                     "tokenizer": "standard",
  15.                     "filter": ["lowercase", "persian_stemmer"]
  16.                 }
  17.             }
  18.         }
  19.     },
  20.     "mappings": {
  21.         "properties": {
  22.             "description": {
  23.                 "type": "text",
  24.                 "analyzer": "persian_analyzer"
  25.             }
  26.         }
  27.     }
  28. }

此示例将创建一个名为“persian_analyzer”的自定义分析器，该分析器使用标准分词器，然后应用小写转换和波斯文词干处理器。描述字段使用此分析器进行分析。请确保您已经安装了“PersianStemmer” Python库，并且已将其集成到您的Elasticsearch环境中。

英文:

I want to create an index for persian-language text and I want to create stemmer for that, this is english-stemming for description field

  1. PUT my_index
  2. {
  3.     "mappings": {
  4.       "properties": {
  5.         "description": {
  6.           "type": "text",
  7.           "analyzer": "english"
  8.         }
  9.       }
  10.     }, 
  11.     "settings": {
  12.       "analysis":{
  13.         "filter": {
  14.           "english_stemmer": {
  15.             "type":       "stemmer",
  16.             "language":   "english"
  17.           }
  18.         }
  19.       }
  20.     }
  21. }

Now I want to know how can implement the PersianStemmer python library to elasticsearch analyzer?

你需要为此创建自定义分析器：

  1. PUT my_index
  2. {
  3.    "settings": {
  4.       "analysis": {
  5.          "filter": {
  6.             "persian_stemmer": {
  7.                "type": "stemmer",
  8.                "language": "persian"
  9.             }
  10.          },
  11.          "analyzer": {
  12.             "persian_analyzer": {
  13.                "tokenizer": "standard",
  14.                "filter": [
  15.                   "lowercase",
  16.                   "persian_stemmer"
  17.                ]
  18.             }
  19.          }
  20.       }
  21.    },
  22.    "mappings": {
  23.       "properties": {
  24.          "description": {
  25.             "type": "text",
  26.             "analyzer": "persian_analyzer"
  27.          }
  28.       }
  29.    }
  30. }
英文:

You need to create custom analyzer for that:

  1.     PUT my_index
  2. {
  3.   "settings": {
  4.     "analysis": {
  5.       "filter": {
  6.         "persian_stemmer": {
  7.           "type": "stemmer",
  8.           "language": "persian"
  9.         }
  10.       },
  11.       "analyzer": {
  12.         "persian_analyzer": {
  13.           "tokenizer": "standard",
  14.           "filter": [
  15.             "lowercase",
  16.             "persian_stemmer"
  17.           ]
  18.         }
  19.       }
  20.     }
  21.   },
  22.   "mappings": {
  23.     "properties": {
  24.       "description": {
  25.         "type": "text",
  26.         "analyzer": "persian_analyzer"
  27.       }
  28.     }
  29.   }
  30. }
