solrJ查詢使用

//AND 並且
    SolrQuery params = new SolrQuery("name:apple AND manu:inc");
    
    //OR 或者
    params.setQuery("name:apple OR manu:apache");
    //空格 等同於 OR
    params.setQuery("name:server manu:dell");
    
    //params.setQuery("name:solr - manu:inc");
    //params.setQuery("name:server + manu:dell");
    
    //查詢name包含solr apple
    params.setQuery("name:solr,apple");
    //manu不包含inc
    params.setQuery("name:solr,apple NOT manu:inc");
    
    //50 <= price <= 200
    params.setQuery("price:[50 TO 200]");
    params.setQuery("popularity:[5 TO 6]");
    //params.setQuery("price:[50 TO 200] - popularity:[5 TO 6]");
    //params.setQuery("price:[50 TO 200] + popularity:[5 TO 6]");
    
    //50 <= price <= 200 AND 5 <= popularity <= 6
    params.setQuery("price:[50 TO 200] AND popularity:[5 TO 6]");
    params.setQuery("price:[50 TO 200] OR popularity:[5 TO 6]");
    
    //過濾器查詢，可以提高性能 filter 類似多個條件組合，如and
    //params.addFilterQuery("id:VA902B");
    //params.addFilterQuery("price:[50 TO 200]");
    //params.addFilterQuery("popularity:[* TO 5]");
    //params.addFilterQuery("weight:*");
    //0 < popularity < 6  沒有等於
    //params.addFilterQuery("popularity:{0 TO 6}");
    
    //排序
    params.addSortField("id", ORDER.asc);
    //分頁：start開始頁，rows每頁顯示記錄條數
    //params.add("start", "0");
    //params.add("rows", "200");
    //params.setStart(0);
    //params.setRows(200);
    
    //設置高亮
    params.setHighlight(true); // 開啓高亮組件
    params.addHighlightField("name");// 高亮字段
    params.setHighlightSimplePre("<font color='red'>");//標記，高亮關鍵字前綴
    params.setHighlightSimplePost("</font>");//後綴
    params.setHighlightSnippets(1);//結果分片數，默認爲1
    params.setHighlightFragsize(1000);//每個分片的最大長度，默認爲100
 
    //分片信息
    params.setFacet(true)
        .setFacetMinCount(1)
        .setFacetLimit(5)//段
        .addFacetField("name")//分片字段
        .addFacetField("inStock"); 
    
    //params.setQueryType("");
