目前Elasticsearch对我来说运行良好，但我希望全文优先于Ngrams。
我尝试了以下内容：
client.indices.create index: index,
body: {
mappings: {
search_variable: {
properties: {
"name" => {
"type" => "string",
"index" => "not_analyzed"
},
"label" => {
"type" => "string",
"index" => "not_analyzed"
},
"value_labels" => {
"type" => "string",
"index" => "not_analyzed"
},
"value_label_search_string" => {
"type" => "string",
"index" => "not_analyzed"
},
"search_text" => {
"type" => "multi_field",
"fields" => {
"whole_words" => {"type" => "string", "analyzer" => "simple"},
"ngram" => {"type" => "string", "analyzer" => "ngram", "search_analyzer" => "ngram_search"}
}
}
}
},
settings: {
analysis: {
filter: {
ngram: {
type: 'nGram',
min_gram: 3,
max_gram: 25
}
},
analyzer: {
ngram: {
tokenizer: 'whitespace',
filter: ['lowercase', 'stop', 'ngram'],
type: 'custom'
},
ngram_search: {
tokenizer: 'whitespace',
filter: ['lowercase', 'stop'],
type: 'custom'
}
}
}
}
}
}
这是与我的全文搜索字段相关的部分：search_text：
"search_text" => {
"type" => "multi_field",
"fields" => {
"whole_words" => {"type" => "string", "analyzer" => "simple"},
"ngram" => {"type" => "string", "analyzer" => "ngram", "search_analyzer" => "ngram_search"}
}
}
我想给与搜索文本中的整个单词匹配的项目提供更高的分数。
[400] {"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"analyzer [ngram_search] not found for field [ngram]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [search_variable]: analyzer [ngram_search] not found for field [ngram]","caused_by":{"type":"mapper_parsing_exception","reason":"analyzer [ngram_search] not found for field [ngram]"}},"status":400}
这是错误：
"reason":"analyzer [ngram_search] not found for field [ngram]"
我做错了什么？
编辑：
这是我的查询，我现在只尝试匹配整个单词，每次只得到0个结果。
search_query = {
index: index,
body: {
_source: {
exclude: ["search_text", "survey_id"]
},
query: {
:bool => {
:filter => {
:term => {"survey_id" => 12}
},
:must => {
:match => {
"search_text.whole_words" => {"query" => "BMW", "operator" => "and"}
}
}
}
}
}
}
result = client.search(search_query)
以下是输出：

索引似乎很奇怪no：
"search_text": {
"type": "string",
"index": "no",
"fields": {
"ngram": {
"type": "string",
"analyzer": "ngram",
"search_analyzer": "ngram_search"
},
"whole_words": {
"type": "string",
"analyzer": "simple"
}
}
}
编辑：以下是“福特”一词的示例匹配文档：
{
"name"=>"car_ownership",
"label"=>"Customer: Ford",
"category"=>["Vehicles", "Passenger Vehicles"], "value"=>nil,
"value_labels"=>{"1"=>"Yes", "2"=>"No"},
"node_id"=>14813,
"survey_id" => 12,
"search_text" => "Customer Ford Vehicles Passenger Vehicles Yes No"
}
编辑：我添加了一个较小的开始结束测试用例，可以在这里找到，它会复制错误。

答案 0 :(得分：1)
第一个问题是在创建索引时settings没有正确嵌套。 settings和mappings应处于同一级别。
然后，查看您的Dropbox文件，我认为问题是映射类型称为search_variable，而在批量中您使用映射类型test_type。因此，永远不会应用映射。
