目录
一、查
1.匹配查询
注意:字符串搜索时,会对输入的查询字符串进行分析和分词,可能导致意外匹配或未匹配。
#搜索
GET /your_index/_search
{
"query": {
"match": {
"news_id" : 100
}}
}
2. 精确匹配字符串
注意:term 查询日期字符串时,因为映射方式不同可能存在匹配不到
GET /your_index/_search
{
"query": {
"term": {
"title.keyword" : "superman"
}}
}
3.匹配某字段为空
GET /your_index/_search
{
"query": {
"term": {
"name.keyword" : ""
}}
}
4.多条件匹配
GET /your_index/_search
{
"query": {
"bool": {
"must": [
