1、match all

查询所有

GET /_search

{

"query": {

"match_all": {}

}

}

示例：

GET /company/employee/_search

{

"query": {

"match_all": {}

}

}

   

2、match

GET /_search

{

"query": { "match": { "title": "my elasticsearch article" }}

}

示例：

GET /company/employee/_search

{

"query": {

"match": {

"age": "27"

}

}

}

   

3、multi match

GET /test_index/test_type/_search

{

"query": {

"multi_match": {

"query": "test",

"fields": ["test_field", "test_field1"]

}

}

}

示例：

GET /company/employee/_search

{

"query": {

"multi_match": {

"query": "china",

"fields": ["address.city","address.country","address.province"]

}

}

}

   

4、range query

GET /company/employee/_search

{

"query": {

"range": {

"age": {

}

}

}

}

{

"query": {

"range": {

"age": {

"gte": 30

}

}

}

}

   

5、term query

不分词，必须精确匹配

GET /test_index/test_type/_search

{

"query": {

"term": {

"test_field": "test hello"

}

}

}

   

6、terms query

不分词，必须精确匹配

{

"query": { "terms": { "tag": [ "search", "full_text", "nosql" ] }}

}
