Elasticsearch java api 常用查询方法QueryBuilder构造举例
环境
Elasticsearch版本
5.1.1
pom
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>5.1.1</version>
</dependency>
Elasticsearch索引方式
数字
{
"type": "long"
}
字符串
{
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
精确查询
以下字段名用${fieldName}代替，具体值用${fieldValue}代替
数字
单个
QueryBuilder qb1 = QueryBuilders.termQuery("${fieldName}", "${fieldValue}");
批量
QueryBuilder qb1 = QueryBuilders.termsQuery("${fieldName}", "${fieldValues}");
字符串
单个
QueryBuilder qb1 = QueryBuilders.termQuery("${fieldName}.keyword", "${fieldValue}");
批量
QueryBuilder qb1 = QueryBuilders.termsQuery("${fieldName}.keyword", "${fieldValues}");
模糊查询
数字
数字查询都为精确查询
字符串
QueryBuilder qb1 = QueryBuilders.moreLikeThisQuery(new String[]{"${fieldName}"}, new String[]{"${fieldValue}"}, null);
范围查询
数字
闭区间查询
QueryBuilder qb1 = QueryBuilders.rangeQuery("${fieldName}").from(${fieldValue1}).to(${fieldValue2});
开区间查询
QueryBuilder qb1 = QueryBuilders.rangeQuery("${fieldName}").from(${fieldValue1}, false).to(${fieldValue2}, false);
大于
QueryBuilder qb1 = QueryBuilders.rangeQuery("${fieldName}").gt(${fieldValue});
大于等于
QueryBuilder qb1 = QueryBuilders.rangeQuery("${fieldName}").gte(${fieldValue});
小于
QueryBuilder qb1 = QueryBuilders.rangeQuery("${fieldName}").lt(${fieldValue});
小于等于
QueryBuilder qb1 = QueryBuilders.rangeQuery("${fieldName}").lte(${fieldValue});
多条件查询
QueryBuilder qb1 = QueryBuilders.moreLikeThisQuery(new String[]{"${fieldName1}"}, new String[]{"${fieldValue1}"}, null);
QueryBuilder qb2 = QueryBuilders.rangeQuery("${fieldName2}").gt("${fieldValue2}");
QueryBuilder qb3 = QueryBuilders.boolQuery().must(qb1).must(qb2);
