导入json文件accounts.json到es中
curl -X POST "localhost:9200/bank/bank_info/_bulk?pretty" -H "Content-Type: application/json" --data-binary "@accounts.json"六、数据检索
- query:指定查询条件，这里使用{ "match_all": {} }表示查询条件匹配所有记录
- from:表示从第n条匹配记录开始取值,默认为0
- size:表示匹配条数，默认10
- sort:表示排序，这里使用{ "balance": { "order": "desc" }},表示按balance降序排序,这里也可以写成[{ "balance": "desc" }]
- _source:表示查询字段，这里使用["account_number", "balance"]表示返回结果中，只需要返回"account_number", "balance"两个字段即可。默认返回所有字段。
curl -X GET "localhost:9200/bank/_search?pretty" -H "Content-Type: application/json" -d '
{
"query":{"match_all":{}},
"from":10,
"size":5,
"sort":[
{"balance":"desc"}
],
"_source":["account_number","balance"]
}
'1、match查询：查询 account_number=20 的document
curl -X GET "localhost:9200/bank/_search?pretty" -H "Content-Type: application/json" -d '
{
"query":{
"match":{"account_number":20}
}
}
'2、match查询：查询 address 中包含 “mill” 的document
curl -X GET "localhost:9200/bank/_search?pretty" -H "Content-Type: application/json" -d '

curl -X GET "localhost:9200/bank/_search?pretty" -H "Content-Type: application/json" -d '
{
"query":{
"match_phrase":{"address":"mill lane"}
}
}
'注意：match与match_phrase的区别
- 对于match的结果，我们可以可以看到，结果的Document中description这个field可以包含“He is”，“He”或者“is”；
- match_phrased的结果中的description字段，必须包含“He is”这一个词组；
- 所有的检索结果都有一个_score字段，看起来是当前这个document在当前搜索条件下的评分，而检索结果也是按照这个得分从高到低进行排序。
5、bool and关系查询：查询address中同时包含“mill”与“lane”的document
curl -X GET "localhost:9200/bank/_search?pretty" -H "Content-Type: application/json" -d '

{
"query":{
"bool":{
"must":[
{"match":{"age":40}}
],
"must_not":[
{"match":{"state":"ID"}}
]
}
}
}
'9、bool filter查询：查询20000<=balance<=30000的document
curl -X GET "localhost:9200/bank/_search?pretty" -H "Content-Type: application/json" -d '
{
"query":{
"bool":{
"filter":{
"range":{
"balance":{
"gte":20000,
"lte":30000
}
}
}
}
}
}
'七、在多索引中搜索
1、同时在bank，teacher两个索引中搜索

{
"query":{
"match_all":{}
}
}'九、query查询条件与filter过滤条件
1、查询“title”中包含“Search”，“content”中包含“Elasticsearch”，“status”为“published”，“publish_date”>2015-01-01的文档
curl -X GET "localhost:9200/_search?pretty" -H "Content-Type: application/json" -d '
{
"query":{
"bool":{
"must”:[
{"match":{"title":"Search"}},
{"match":{"content":"Elasticsearch"}}
],
"filter":[
{"term":{"status":"published"}},
{"range":{"publish_date":{"gte":"2015-01-01"}}}
]
}
}
}'十、从多个字段中搜索 multi_match
1、从"title","content"中搜索"learn"
curl -X GET "localhost:9200/website/_search?pretty" -H "Content-Type: application/json" -d '
