我有一些我想要使用的推特数据。我希望能够搜索一个名字。当试图生成名称'和' _id'我遇到了一些麻烦。
首先,我创建了分析器:
curl -XPUT 'localhost:9200/twitter_users' -d '
{
"settings": {
"analysis": {
"analyzer": {
"str_search_analyzer": {
"tokenizer": "keyword",
"filter": [
"lowercase"
]
},
"str_index_analyzer": {
"tokenizer": "keyword",
"filter": [
"lowercase",
"ngram"
]
}
},
"filter": {
"ngram": {
"type": "ngram",
"min_gram": 3,
"max_gram": 20
}
}
}
}
}'
然后我定义了我的映射:
curl -XPUT 'http://localhost:9200/twitter_users/users/_mapping' -d '
{
"users": {
"type" : "object",
"properties": {
"_id": {
"type": "string",
"copy_to": "id"
},
"id": {
"type": "string",
"search_analyzer": "str_search_analyzer",
"index_analyzer": "str_index_analyzer",
"index": "analyzed"
},
"name": {
"type": "multi_field",
"fields": {
"name": {
"type": "string",
"index": "not_analyzed"
},
"ngrams": {
"type": "string",
"search_analyzer": "str_search_analyzer",
"index_analyzer": "str_index_analyzer",
"index": "analyzed"
}
}
}
}
}
}'
并插入一些测试数据:
curl -XPUT "localhost:9200/twitter_users/users/johndoe" -d '{
"_id" : "johndoe",
"name" : "John Doe"
}'
curl -XPUT "localhost:9200/twitter_users/users/janedoe" -d '{
"_id" : "janedoe",
"name" : "Jane Doe"
}'
按名称查询可以获得预期的结果:
curl -XPOST "http://localhost:9200/twitter_users/users/_search" -d '{
"query": {
"match": {
"name.ngrams": "doe"
}
}
}'
但是查询id却没有给我带来任何结果:
curl -XPOST "http://localhost:9200/twitter_users/users/_search" -d '{
"query": {
"match": {
"id": "doe"
}
}
}'
我还测试过_id是一个多字段,就像我用名字一样。但那也没有用。
_id的行为与其他字段不同?或者我在这里做错了什么?
编辑:使用elasticsearch v1.1.2并使用河流插件从mongodb中提取数据。
感谢您的帮助

看起来像'copy_to'是问题,但为什么不插入' id'价值进入' id'直接领域?
curl -XPUT "localhost:9200/twitter_users/users/johndoe" -d '{
"id" : "johndoe",
"name" : "John Doe"
}'
curl -XPUT "localhost:9200/twitter_users/users/janedoe" -d '{
"id" : "janedoe",
"name" : "Jane Doe"
}'
