查询时的api分为两种一种是万能的set,还有一种是setxxxquery

 1     @Test
 2     public void search2() throws Exception{
 3         HttpSolrClient solrClient  = new HttpSolrClient.Builder("http://127.0.0.1:8080/solr/solrcore1").build();
 4         SolrQuery query = new SolrQuery();
 5         query.set("q","test001");
 6         
 7         
 8         //1.过滤器
 9         query.set("fq","pprice:[1 TO 100]");//query.setFilterQueries("pprice:[1 TO 100]");也可以用addFiterQuries设置多过滤条件
10         
11         //2.排序
12         query.set("sort","pprice desc,id asc");//query.setSort("pprice",ORDER.desc);  addSort
13         
14         
15         //3.设置查询到的文档返回的域对象
16         query.set("fl","id,pname,pprice");//query.setFields("id,pname");
17         
18         //4.设置默认查询的域
19         query.set("df","pname");
20         
21         //5.分页
22         query.set("start",0);  //query.setStart(0)
23         query.set("rows",5);   //query.setRows(5)
24         
25         //6.高亮
26         query.set("hl",true);
27         //设置高亮域(设置的域必须在查询条件中存在)
28         query.set("h1.fl","pname","pprice");
29         //前缀
30         query.set("hl.simple.pre","<em style=‘color:red‘>");
31         //后缀
32         query.set("hl.simple.post","</em>");
33         
34         /*query.setHighlight(true);
35         query.addHighlightField("pname");
36         query.setHighlightSimplePre("<em style=‘color:red‘>");
37         query.setHighlightSimplePost("</em>");*/
38 
39         
40         QueryResponse response = solrClient.query(query);
41         SolrDocumentList results = response.getResults();
42         //k是id,内部的map的key是域名,其value是高亮的值集合
43         Map<String, Map<String, List<String>>> highlighting = response.getHighlighting();
44         System.out.println("匹配的结果总数是-------"+results.getNumFound());
45         for(SolrDocument document:results) {
46             System.out.println("id----" + document.get("id"));
47             System.out.println("pname-----" + document.get("pname"));
48             System.out.println("pprice------" + document.get("pprice"));
49             List<String> list = null;
50             if(highlighting.get(document.get("id")) != null) {
51                list = highlighting.get(document.get("id")).get("pname");
52             }else {
53                 System.out.println("无法获取高亮map");
54             }
55             
56             if (list != null && list.size() > 0) {
57                 System.out.println("高亮显示的内容:----"+list.get(0));
58             }else {
59                 System.out.println("高亮显示的内容为空!!!");
60             }
61             System.out.println("=========================");
62         }
63     }
