如何解决Elasticsearch - 按字段获取结果摘要
{"name": "John","district": 1,"light": 2},{"name": "John","district": 5,"light": 27},"district": 11,"light": 1},"light": 0},"light": 10},"district": 8,"light": 6},{"name": "Mary","district": 2,{"name": "Nick",{"name": "Bob","district": 3,{"name": "Kenny","light": 8}
示例:
搜索时
"query": {
"term": {
"name": {
"value": "john"
}
}
}
预期输出:
{
"district": {
11: 3,// value : the amount of matches
5: 2,1: 1,},"light": {
2: 2,// value : the amount of matches
27: 1,10: 1,// etc..
}
}
解决方法
尝试一对术语聚合:
{
"size": 0,"query": {
"term": {
"name": {
"value": "john"
}
}
},"aggs": {
"by_district": {
"terms": {
"field": "district"
}
},"by_light": {
"terms": {
"field": "light"
}
}
}
}
