 BooleanQuery.Builder bqBuilder = new BooleanQuery.Builder();
 if(!StringUtils.isEmpty(name)){
 SmartChineseAnalyzer analyzer=new SmartChineseAnalyzer();//中文
 QueryParser parser=new QueryParser("name", analyzer);
 Query query = parser.parse(name);
 bqBuilder.add(query,Occur.MUST);
 }
 if(!StringUtils.isEmpty(provId)){
 bqBuilder.add(new TermQuery(new Term("provinceId",provId)), Occur.MUST);
 }
 if(!StringUtils.isEmpty(cityId)){
 bqBuilder.add(new TermQuery(new Term("cityId",cityId)), Occur.MUST);
 }
 if(!StringUtils.isEmpty(unionNumber)){
 bqBuilder.add(new TermQuery(new Term("unionNumber",unionNumber)), Occur.MUST);
 } 
 if(!StringUtils.isEmpty(bankType)){
 bqBuilder.add(new TermQuery(new Term("bankType",bankType)), Occur.MUST);
 } 
 if(CollectionUtils.isEmpty(bqBuilder.build().clauses())){
 bqBuilder.add(new WildcardQuery(new Term("name","*")),BooleanClause.Occur.SHOULD);
 }

 BooleanQuery bQuery = bqBuilder.build();
