我测试了一下多字段构造查询，代码如下：
try {
long start=System.currentTimeMillis();
Directory dic = new SimpleFSDirectory(new File(ILuceneManager.DEFAULT_REGION_LUCENE_INDEX_PATH));
IndexSearcher searcher=new IndexSearcher(dic);
//----------设置相似度
//searcher.setSimilarity(new IKSimilarity());
//-----------多字段查询 经过测试StandardAnalyzer分词器要比IKAnalyzer的效率要快
Analyzer analyzer=new StandardAnalyzer(Version.LUCENE_CURRENT);
//Analyzer analyzer=new IKAnalyzer(true);
String[] fields=new String[]{"NAME","USERNAME","weight","STANDARDNAME","ADDRESS"};
MultiFieldQueryParser multiQParser=new MultiFieldQueryParser(Version.LUCENE_CURRENT, fields, analyzer);
//----------关键字
String keyword="?府 ";
Query query=multiQParser.parse(keyword);
//------------查询
//searcher.search(query, LuceneManagerImpl.DEFAULT_QUERY_NUM);
TopDocs tops=searcher.search(query,10);
ScoreDoc[] scores=tops.scoreDocs;
int length=tops.totalHits;
for(int i=0;i<(length>LuceneManagerImpl.DEFAULT_QUERY_NUM?LuceneManagerImpl.DEFAULT_QUERY_NUM:length);i++){
Document targetDoc=searcher.doc(scores[i].doc);
//System.out.println(targetDoc.getFields("NAME")[0].stringValue());
//System.out.println(targetDoc.getFields("ADDRESS")[0].stringValue());
//System.out.println(targetDoc.get("NAME"));
System.out.println(targetDoc.get("ADDRESS"));
System.out.println(targetDoc.get("USERNAME"));
System.out.println(targetDoc.get("NAME"));
};
long end=System.currentTimeMillis();
System.out.println("搜索共耗时:"+(end-start)+" 毫秒");
我搜索关键字是：“?府”。结果后台直接报错，错误信息如下：

由错误信息提示，让我记住了，使用WildCardQuery对象进行查询时，查询关键字前不能有“？”和“*”。
