如何编写单个Elasticsearch查询,该查询将计算有多少文档具有某个字段的值或缺少该字段?
此查询成功地计算出docst 缺少的字段:
POST localhost:9200//<index_name_here>/_search
{
"size": 0,
"aggs" : {
"Missing_Field" : {
"missing": { "field": "group_doc_groupset_id" }
}
}
}
此查询的操作与此相反,计数文档而不缺少字段:
POST localhost:9200//<index_name_here>/_search
{
"size": 0,
"aggs" : {
"Not_Missing_Field" : {
"exists": { "field": "group_doc_groupset_id" }
}
}
}
我怎么写一个结合了两者的书?例如,这产生语法错误:
POST localhost:9200//<index_name_here>/_search
{
"size": 0,
"aggs" : {
"Missing_Field_Or_Not" : {
"missing": { "field": "group_doc_groupset_id" },
"exists": { "field": "group_doc_groupset_id" }
}
}
}
最佳答案
GET indexname/_search?size=0
{
"aggs": {
"a1": {
"missing": {
"field": "status"
}
},
"a2": {
"filter": {
"exists": {
"field": "status"
}
}
}
}
}
关于elasticsearch - 在Elasticsearch中计算有多少个文档具有属性或缺少该属性,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/37929836/
