问题:如何使用
从json文件创建索引 json文件包含索引de_brochures
的定义。它还定义了一个分析器de_analyzer
,其中包含相应索引使用的自定义过滤器。
由于json使用curl和Sense,我假设我必须调整它的语法以使用java API。
我不想使用XContentFactory.jsonBuilder(),因为json来自一个文件!
我有以下json文件来创建我的映射和设置设置:
使用Sense和PUT / indexname,它确实从中创建了一个索引。
{
"mappings": {
"de_brochures": {
"properties": {
"text": {
"type": "string",
"store": true,
"index_analyzer": "de_analyzer"
},
"classification": {
"type": "string",
"index": "not_analyzed"
},
"language": {
"type": "string",
"index": "not_analyzed"
}
}
}
"settings": {
"analysis": {
"filter": {
"de_stopwords": {
"type": "stop",
"stopwords": "_german_"
},
"de_stemmer": {
"type": "stemmer",
"name": "light_german"
}
},
"analyzer": {
"de_analyzer": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"de_stopwords",
"de_stemmer"
]
}
}
}
}
}
由于以上单独使用addMapping()无效,我尝试将其拆分为两个单独的文件(我意识到我必须删除"mappings":
和"settings":
部分):
------ Mapping json ------
{
"de_brochures": {
"properties": {
"text": {
"type": "string",
"store": true,
"index_analyzer": "de_analyzer"
},
"classification": {
"type": "string",
"index": "not_analyzed"
},
"language": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
------- Settings json --------
{
"analysis": {
"filter": {
"de_stopwords": {
"type": "stop",
"stopwords": "_german_"
},
"de_stemmer": {
"type": "stemmer",
"name": "light_german"
}
},
"analyzer": {
"de_analyzer": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"de_stopwords",
"de_stemmer"
]
}
}
}
}
这是我加载和添加/设置json的java代码。
CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate(index);
// CREATE SETTINGS
String settings_json = new String(Files.readAllBytes(brochures_mapping_path));
createIndexRequestBuilder.setSettings(settings_json);
// CREATE MAPPING
String mapping_json = new String(Files.readAllBytes(brochures_mapping_path));
createIndexRequestBuilder.addMapping("de_brochures", mapping_json);
CreateIndexResponse indexResponse = createIndexRequestBuilder.execute().actionGet();
没有关于映射文件结构的抱怨,但它现在失败并出现错误:
Caused by: org.elasticsearch.index.mapper.MapperParsingException: Analyzer [de_analyzer] not found for field [text]

我设法使用createIndexRequestBuilder.setSource(settings_json);

我认为问题在于您的映射文件的结构。
以下是一个示例。
mapping.json
{
"en_brochures": {
"properties": {
"text": {
"type": "string",
"store": true,
"index_analyzer": "en_analyzer",
"term_vector": "yes"
},
"classification": {
"type": "string",
"index": "not_analyzed"
},
"language": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
String mapping = new String(Files.readAllBytes(Paths.get("mapping.json")));
createIndexRequestBuilder.addMapping('en_brochures', mapping);
CreateIndexResponse indexResponse =createIndexRequestBuilder.execute().actionGet();
这在我的作品中有效,你可以试试。
