我无法在嵌套对象中找到单词的某些部分。只找到完整的单词。我的分析仪配置如下：
{
"settings": {
"number_of_shards": 1,
"analysis": {
"filter": {
"word_part_filter": {
"type": "ngram",
"min_gram": 3,
"max_gram": 15
},
"word_part_front_filter": {
"type": "edgeNGram",
"min_gram": 2,
"max_gram": 15
},
"codeid_filter": {
"type": "pattern_replace",
"pattern": "[-/.:]",
"replacement": "",
"preserve_original": true
}
},
"char_filter": {
"umlaut_char_filter": {
"type": "mapping",
"mappings": [
"ö=>oe",
"ä=>ae",
"ü=>ue",
"Ã?=>ss",
"Ã?=>Oe",
"Ã?=>Ae",
"Ã?=>Ue"
]
}
},
"analyzer": {
"description_analyser_query": {
"type": "custom",
"char_filter": [
"html_strip"
],
"tokenizer": "standard",
"filter": [
"lowercase",
"stop",
"asciifolding"
]
},
"description_analyser_idx": {
"type": "custom",
"char_filter": [
"html_strip"
],
"tokenizer": "standard",
"filter": [
"lowercase",
"stop",
"asciifolding",
"word_part_filter"
]
},
"name_analyser_query": {
"type": "custom",
"char_filter": [
"umlaut_char_filter"
],
"tokenizer": "standard",
"filter": [
"lowercase",
"asciifolding"
]
},
"name_analyser_idx": {
"type": "custom",
"char_filter": [
"umlaut_char_filter"
],
"tokenizer": "standard",
"filter": [
"lowercase",
"asciifolding",
"word_part_filter"
]
},
"codeid_analyser_query": {
"type": "custom",
"tokenizer": "keyword",
"filter": [
"lowercase",
"codeid_filter"
]
},
"codeid_analyser_idx_front": {
"type": "custom",
"tokenizer": "keyword",
"filter": [
"lowercase",
"codeid_filter",
"word_part_front_filter"
]
},
"codeid_analyser_idx_any": {
"type": "custom",
"tokenizer": "keyword",
"filter": [
"lowercase",
"codeid_filter",
"word_part_filter"
]
}
}
}
}
}
这是嵌套对象映射（已提取）：
{
"properties": {
"aid": {
"type": "nested",
"properties": {
"tpid": {
"type": "string",
"analyzer": "codeid_analyser_idx_any"
},
"aid": {
"type": "string",
"analyzer": "codeid_analyser_idx_any"
}
}
}
}
}
我正在搜索此查询（摘录）。只有＆＃34;嵌套＆＃34;部分是必不可少的：
{
"query": {
"bool": {
"must": [
{
"bool": {
"should": [
{
"nested": {
"path": "aid",
"query": {
"bool": {
"must": {
"match": {
"aid.aid": {
"query": "1200",
"analyzer": "codeid_analyser_query"
}
}
},
"filter": {
"or": [
{
"match": {
"aid.tpid": "buyer_specific"
}
},
{
"match": {
"aid.tpid": "mytpid"
}
}
]
}
}
}
}
}
],
"minimum_should_match": 1
}
}
]
}
}
}
有一个元素，辅助= 120000008
在字段中使用分析器时，它什么也没找到。在嵌套对象映射和查询中根本不使用分析器时，只能找到完整的单词（例如＆＃34; 120000008＆＃34;），但不会找到＆＃34; 1200＆＃34;。有什么想法吗？
答案 0 :(得分：5)
实际上，使用ElasticSearch 5.2，使用名为test的索引，并在名为＆＃34; product＆＃34;的类型上应用映射。 （只重写过滤器部分，使其符合查询语言的演变），我得到了正确的结果。查询：
GET test/_search
{
"query": {
"bool": {
"must": [
{
"bool": {
"should": [
{
"nested": {
"path": "aid",
"query": {
"bool": {
"must": {
"match": {
"aid.aid": {
"query": "1200",
"analyzer": "codeid_analyser_query"
}
}
},
"filter": {
"terms": {
"aid.tpid": [
"mytpid",
"buyer_specific"
]
}
}
}
}
}
}
],
"minimum_should_match": 1
}
}
]
}
}
}
索引：
GET test/_search
{
"took": 8,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "test",
"_type": "product",
"_id": "AVrJ1CSd-NyeQ4r64kP6",
"_score": 1,
"_source": {
"aid": {
"aid": "120000008",
"tpid": "mytpid"
}
}
}
]
}
}
分析仪（我删除了变音过滤器，因为它在我的计算机上无法读取，并且它不会像测试中那样改变结果）：
PUT test
{
"settings": {
"analysis": {
"filter": {
"word_part_filter": {
"type": "ngram",
"min_gram": 3,
"max_gram": 15
},
"word_part_front_filter": {
"type": "edgeNGram",
"min_gram": 2,
"max_gram": 15
},
"codeid_filter": {
"type": "pattern_replace",
"pattern": "[-/.:]",
"replacement": "",
"preserve_original": true
}
},
"analyzer": {
"description_analyser_query": {
"type": "custom",
"char_filter": [
"html_strip"
],
"tokenizer": "standard",
"filter": [
"lowercase",
"stop",
"asciifolding"
]
},
"description_analyser_idx": {
"type": "custom",
"char_filter": [

"tokenizer": "standard",

},
"codeid_analyser_query": {

"codeid_analyser_idx_front": {

产品上的映射：
PUT test/_mapping/product
{
"properties": {
"aid": {
"type": "nested",
"properties": {
"tpid": {
"type": "string",
"analyzer": "codeid_analyser_idx_any"
},
"aid": {
"type": "string",
"analyzer": "codeid_analyser_idx_any"
}
}
}
}
