java.sql.SQLException: Geometry byte string must b…

I want to use the contains function to get all values whose title or question contains a certain value. However, I get this error:

This is the code:

public String getRecentQuestions(String search) throws SQLException {
        PreparedStatement ps=con.prepareStatement("select title, question_id from questions where contains(title, ?) or contains(question, ?) limit 20");
        ps.setString(1, search);
        ps.setString(2, search);
        ResultSet rs=ps.executeQuery();
        StringBuilder sb=new StringBuilder("");
        while (rs.next()) {
            sb.append("<a href='Question.jsp?question=").append(rs.getInt(2)).append("'><h2>");
            sb.append(rs.getString(1));
            sb.append("</h2></a>");
        }
        return sb.toString();
    }

My PreparedStatement is valid, the title column data type is varchar, and the question column data type is varchar as well. Thanks in advance.
