目前的需求是假如我要知道2018-04-02,2018-04-03号的pageView之和,很明显需要ebayTrackList.date过滤求和ebayTrackList.pageView字段
语句如下
{ "query":{ "bool" : { "must" : [ { "term" : {"itemId":"132417862061"} }, { "nested" : { "path" : "ebayTrackList", "query" : { "bool" : { "must" : [ { "terms" : {"ebayTrackList.date" : ["2018-04-03","2018-04-02"]} } ] } } } } ] } }, "aggs":{ "numTotalCount" : { "nested" : { "path" : "ebayTrackList" }, "aggs" : { "sd_value" : { "filter" : { "terms" : {"ebayTrackList.date" : ["2018-04-03","2018-04-02"]} }, "aggs" : { "sum_count" : { "sum" : { "field" : "ebayTrackList.pageView" } } } } } } } }
