示例1: DoSearching

		public virtual void  DoSearching(Query unReWrittenQuery)
		{
			searcher = new IndexSearcher(ramDir);
			//for any multi-term queries to work (prefix, wildcard, range,fuzzy etc) you must use a rewritten query!
			query = unReWrittenQuery.Rewrite(reader);
			System.Console.Out.WriteLine("Searching for: " + query.ToString(FIELD_NAME));
			hits = searcher.Search(query);
