luence7.0.0 搜索负数怎么搜索，用QueryParser搜索，我要搜索retype为-1的

Analyzer analyzer = new StandardAnalyzer();
QueryParser parser = new QueryParser("", analyzer);
StringBuffer searchStr = new StringBuffer();
searchStr.append("isfirst:\"0\"");
searchStr.append(" AND ");
searchStr.append("rmproj:\"123\"");
searchStr.append(" AND ");
searchStr.append("retype:\"-1\"");
searchStr.append(" NOT ");
searchStr.append("rmqid:\"1\"");
Query query = parser.parse(searchStr.toString());
