• solr 查询同一个core 的关联字段


    实现一个core里面多个字段的关联查询:

    应用场景是: 词, 句子,文章

    希望通过查询实现词,句子,文章里面共同有的关键字

    private static CloudSolrServer cloudSolrServer;
        
        private static String zkHost = "192.168.0.157:2181";
        private static CloudSolrServer solrServer = new CloudSolrServer(zkHost);
        private static synchronized CloudSolrServer getCloudSolrServer(
                final String zkHost) {
            if (cloudSolrServer == null) {
                try {
                    cloudSolrServer = new CloudSolrServer(zkHost);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
    
            return cloudSolrServer;
        }
    
    public static Map<String, Object> solrCloudR(String skey,  int start, int rows) throws SolrServerException{
            Map<String, Object> mapResults = new HashMap<String, Object>();
            solrServer.setDefaultCollection("collection1");
            SolrQuery solrQuery = new SolrQuery();
              solrQuery.set("q","word:"+skey+" OR  nickname:"+skey+" OR  content:"+skey);
                solrQuery.setHighlight(true); // 开启高亮组件  
            solrQuery.addHighlightField(skey);// 高亮字段  
            solrQuery.setHighlightSimplePre("<font color='red'>");//标记,高亮关键字前缀  
            solrQuery.setHighlightSimplePost("</font>");//后缀 
            solrQuery.set("start", start);
            solrQuery.set("rows", rows);
            QueryResponse response = solrServer.query(solrQuery);
            SolrDocumentList results = response.getResults();
            long numFound = response.getResults().getNumFound();
            mapResults.put("results:", results);
            System.out.println("numFound=" +numFound);
            for (int i = 0; i < results.size(); ++i) { 
                System.out.println(results.get(i)); 
            } 
            return mapResults;
    }
    
    public static void main(String[] args) throws Exception {
            String skey = "厦门";
            //solrCloudR(skey);
            //solrCloudR(skey);
            //solrSearch(skey, 1, 20);
            solrCloudR(skey, 0, 1000);
            
        }

     查询结果:

    numFound=5
    SolrDocument{createtime=Mon Aug 24 14:58:59 PDT 2015, id=502, articlenum=0, sex=true, username=ad, updatetime=Mon Aug 24 16:19:31 PDT 2015, nickname=厦门, wordnum=0, sentencenum=0, money=0.0, _version_=1510384955694252032}
