關於Lucene分組查詢後的排序

int total = 0;

if (groupfield != null) 
// 如果不分組，直接對查詢結果進行返回
topdocs topfielddocs = null;
if (!"".equals(util.strnull(sortfield))) else if (sortfield.startswith("nprice")) 
topfielddocs = searcher.search(query, end, new sort(new sortfield(sortfield, type, desc)));
} else 
total = topfielddocs.totalhits;

爛掉一塌糊塗 ，不在解釋！~
