Solr之高亮显示yellowcong

Solr高亮显示&＃xff0c;通过高亮显示&＃xff0c;来将重要的数据显示出来。高亮显示&＃xff0c;在WEB的查询和检索中&＃xff0c;会经常的用到&＃xff0c;我们需要通过高亮的操作来显示关键字。操作的时候&＃xff0c;将高亮的数据处理后&＃xff0c;封装成对象后&＃xff0c;再返回给调用者。

案例

通过SolrQuery 设定高亮的效果&＃xff0c;设定高亮的效果可以是加红&＃xff0c;或则是粗体等。

public static void highlight() throws Exception {SolrServer server &＃61; new HttpSolrServer(SOLR_PATH);SolrQuery solrQuery &＃61; new SolrQuery();solrQuery.add("q", "content&＃xff1a;关系");// 开启高亮solrQuery.setHighlight(true);// 高亮显示的格式solrQuery.setHighlightSimplePre("");solrQuery.setHighlightSimplePost("");// 我需要那几个字段进行高亮solrQuery.setParam("hl.fl", "content");QueryResponse response &＃61; server.query(solrQuery);// 直接获取的反回结果SolrDocumentList docs &＃61; response.getResults();for (SolrDocument doc : docs) {String author &＃61; doc.get("author").toString();String content &＃61; doc.get("content").toString();System.out.println(author);System.out.println(content);}System.out.println("-------------------高亮显示效果---------------------------");// 高亮显示的反回结果Map>> maplist &＃61; response.getHighlighting();// 返回高亮之后的结果..for (SolrDocument solrDocument : docs) {Object id &＃61; solrDocument.get("id");Map> fieldMap &＃61; maplist.get(id);List stringlist &＃61; fieldMap.get("content");System.out.println(stringlist);}
}
