1、為帖子數(shù)據(jù)增加tag字段
POST /forum/article/_bulk
{ "update": { "_id": "1"} }
{ "doc" : {"tag" : ["java", "hadoop"]} }
{ "update": { "_id": "2"} }
{ "doc" : {"tag" : ["java"]} }
{ "update": { "_id": "3"} }
{ "doc" : {"tag" : ["hadoop"]} }
{ "update": { "_id": "4"} }
{ "doc" : {"tag" : ["java", "elasticsearch"]} }
2晤碘、搜索articleID為KDKE-B-9947-#kL5或QQPX-R-3956-#aD8的帖子聂宾，搜索tag中包含java的帖子
GET /forum/article/_search
{
"query": {
"constant_score": {
"filter": {
"terms": {
"articleID.keyword": [
"KDKE-B-9947-#kL5",
"QQPX-R-3956-#aD8"
]
}
}
}
}
}
GET /forum/article/_search
{
"query" : {
"constant_score" : {
"filter" : {
"terms" : {
"tag" : ["java"]
}
}
}
}
}
3、優(yōu)化搜索結果都办，僅僅搜索tag只包含java的帖子
POST /forum/article/_bulk
{ "update": { "_id": "1"} }
{ "doc" : {"tag_cnt" : 2} }
{ "update": { "_id": "2"} }
{ "doc" : {"tag_cnt" : 1} }
{ "update": { "_id": "3"} }
{ "doc" : {"tag_cnt" : 1} }
{ "update": { "_id": "4"} }
{ "doc" : {"tag_cnt" : 2} }
GET /forum/article/_search
{
"query": {
"constant_score": {
"filter": {
"bool": {
"must": [
{
"term": {
"tag_cnt": 1
}
},
{
"terms": {
"tag": ["java"]
}
}
]
}
}
}
}
}
