Features
This article will use solr complete vip Ranking, here is not simply ordered by vip level. But when using solr query conditions (without using the sort) will meet the conditions and have a vip level data displayed on the front, this time we will use a custom scoring mechanism underlying solr provided to complete.
Environment Introduction
Development Environment : IDEA + SpringBoot S OLR environment : solr4.10 + tomcat7

@Test
public void defualtQuerySort() throws Exception{ SolrQuery solrQuery = new SolrQuery();
//关键词
solrQuery.set("q","t_searchText:*三星*");
//分页，0开始，每页10条，setStart设置的就是显示第几页

System.out.println("id:"+id+" 标题:"+title+" 评价："+assess+ "点击率："+point+" vip等

}
}The results are as follows:
