1.异常原因

在搜索的时候没有对搜索的内容进行转义。

       String intro = infomationSearchReqVO.getIntro();
        //转义特殊字符
        String searchIntro = QueryParser.escape(intro);

官方文档上写的很清楚，获取一个被转义后的字符串。

escape
public static String escape(String s)
Returns a String where those characters that QueryParser expects to be escaped are escaped by a preceding \.
返回一个String，其中QueryParser期望被转义的那些字符被前面的转义\。
