[英]Python Elasticsearch: Errors when trying to apply an analyzer to Index documents
So I'm trying to apply an analyzer to my index but no matter what I do I get some sort of error.所以我试图将分析器应用于我的索引,但无论我做什么,我都会遇到某种错误。 I've been looking stuff up all day but can't get it to work.我整天都在找东西,但无法正常工作。 If I run it as it is below, I get an error which says如果我按照下面的方式运行它,我会收到一个错误,上面写着
elasticsearch.exceptions.RequestError: RequestError(400, 'illegal_argument_exception', 'analyzer [{settings={analysis={analyzer={filter=[lowercase], type=custom, tokenizer=keyword}}}}] has not been configured in mappings')
if I add a "mappings" below the body= part of the code and above the "properties" part, I get this error如果我在代码的 body= 部分下方和“属性”部分上方添加一个“映射”,我会收到此错误
elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'Root mapping definition has unsupported parameters: [mappings: {properties={Name={analyzer={settings={analysis={analyzer={filter=[lowercase], type=custom, tokenizer=keyword}}}}
(and it'll go through every name in the body part of the code) elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'Root mapping definition has unsupported parameters: [mappings: {properties={Name={analyzer={settings={analysis={analyzer={filter=[lowercase], type=custom, tokenizer=keyword}}}}
(它将 go 通过代码正文部分的每个名称)
def text_normalization():
normalization_analyzer = {
"settings": {
"analysis": {
"analyzer": {
"type": "custom",
"tokenizer": "keyword",
"filter": ["lowercase"]
}
}
}
}
elasticsearch.indices.put_mapping(
index=index_name,
body={
"properties": {
"Year of Birth": {
"type": "integer",
},
"Name": {
"type": "text",
"analyzer": normalization_analyzer
},
"Status": {
"type": "text",
"analyzer": normalization_analyzer
},
"Country": {
"type": "text",
"analyzer": normalization_analyzer
},
"Blood Type": {
"type": "text",
"analyzer": normalization_analyzer
}
}
}
)
match_docments = elasticsearch.search(index=index_name, body={"query": {"match_all": {}}})
print(match_docments)
Any help would be appreciated.任何帮助,将不胜感激。
Your analyzer is simply missing a name, you should specify it like this:您的分析器只是缺少一个名称,您应该像这样指定它:
normalization_analyzer = {
"settings": {
"analysis": {
"analyzer": {
"normalization_analyzer": { <--- add this
"type": "custom",
"tokenizer": "keyword",
"filter": ["lowercase"]
}
}
}
}
}
You need to install this analyzer using您需要使用安装此分析器
elasticsearch.indices.put_settings(...)
Also in the mappings section, you need to reference the analyzer by name, so you simply need to add the analyzer name as a string同样在映射部分,您需要按名称引用分析器,因此您只需将分析器名称添加为字符串
body={
"properties": {
"Year of Birth": {
"type": "integer",
},
"Name": {
"type": "text",
"analyzer": "normalization_analyzer"
},
"Status": {
"type": "text",
"analyzer": "normalization_analyzer"
},
"Country": {
"type": "text",
"analyzer": "normalization_analyzer"
},
"Blood Type": {
"type": "text",
"analyzer": "normalization_analyzer"
}
}
}
