Solr復雜條件查詢

solr復雜查詢條件查詢（排序、過濾、高亮）

簡單案例：

package cn.kingdee;

import java.util.List;
import java.util.Map;

import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.SolrQuery.ORDER;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.impl.HttpSolrServer;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrDocument;
import org.apache.solr.common.SolrDocumentList;
import org.junit.Test;

public class TestMyMannager {
    @Test
    public void queryIndex() throws Exception {
        //創建連接
        SolrServer solrServer = new HttpSolrServer("http://localhost:8080/solr");
        //創建一個query對象
        SolrQuery solrQuery = new SolrQuery();
        //設置默認的查詢范圍
        solrQuery.set("df", "product_name");
        //設置查詢條件
        solrQuery.setQuery("台燈");
        //設置過濾條件
        solrQuery.setFilterQueries("product_catalog_name:幽默雜貨");
        //設置排序條件
        solrQuery.setSort("product_price",ORDER.desc);
        //分頁處理
            //開始索引為0
        solrQuery.setStart(0);
            //每頁顯示多少行
        solrQuery.setRows(8);
        //設置高亮(開啟)
        solrQuery.setHighlight(true);
        //設置高亮域
        solrQuery.addHighlightField("product_name");
        //設置高亮前綴
        solrQuery.setHighlightSimplePre("<em>");
        //設置高亮后綴
        solrQuery.setHighlightSimplePost("</em>");
        //執行語句
        QueryResponse query = solrServer.query(solrQuery);
        //取到查詢結果集
        SolrDocumentList results = query.getResults();
        //共查詢到商品數量
        long numFound = results.getNumFound();
        //遍歷結果
         String productname="";
        for (SolrDocument doc : results) {
            Map<String, Map<String, List<String>>> highlighting = query.getHighlighting();
            List<String> list = highlighting.get(doc.get("id")).get("product_name");
            if (list!=null&&list.size()>0) {
               productname = list.get(0);
            }else{
                productname=(String) doc.get("product_name");
            }
            System.out.println(doc.get("id"));

 


            System.out.println(doc.get("product_name"));
        }
        
    }

}
