根据字段查询，模糊查询，只要包含mill,lane：
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"query": { "match": { "address": "mill lane" } }
}
'
按照短语模糊查找：
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"query": { "match_phrase": { "address": "mill lane" } }
}
'
多条件查询
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" } }
]
}
}
}
'
过滤：
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"query": {
"bool": {
"must": { "match_all": {} },
"filter": {
"range": {
"balance": {
"gte": 20000,
"lte": 30000
}
}
}
}
}
}

聚和操作分组：
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"size": 0,
"aggs": {
"group_by_state": {
"terms": {
"field": "state.keyword"
}
}
}
}
'
分组state求平均值balance：
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"size": 0,
"aggs": {
"group_by_state": {
"terms": {
"field": "state.keyword"
},
"aggs": {
"average_balance": {
"avg": {
"field": "balance"
}
}
}
}
}
}
'
聚合中指定顺序来使用嵌套聚合的结果进行排序
curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'
{
"size": 0,
"aggs": {
"group_by_state": {
"terms": {
"field": "state.keyword",
"order": {
"average_balance": "desc"
}
},
"aggs": {
"average_balance": {
"avg": {
"field": "balance"
}
}
}
}
}
