Delete By Query API
通过查询条件删除
BulkByScrollResponse response =
DeleteByQueryAction.INSTANCE.newRequestBuilder(client)
.filter(QueryBuilders.matchQuery("gender", "male")) //查询条件
.source("persons") //index(索引名)
.get(); //执行
long deleted = response.getDeleted(); //删除文档的数量
如果需要执行的时间比较长,可以使用异步的方式处理,结果在回调里面获取
DeleteByQueryAction.INSTANCE.newRequestBuilder(client)
.filter(QueryBuilders.matchQuery("gender", "male")) //查询
.source("persons") //index(索引名)
.execute(new ActionListener<BulkByScrollResponse>() { //回调监听
@Override
public void onResponse(BulkByScrollResponse response) {
long deleted = response.getDeleted(); //删除文档的数量
}
@Override
public void onFailure(Exception e) {
// Handle the exception
}
});
