Questions for running sentence query

[YuSheng-00]

Thanks very much for sharing your work. But I'm sorry that I have some coding questions that I would like to ask you.
On the line 126 of the file sentence_query.py , the function q.match() is passed a arguments which is an instance of Index Class. However, for a Query object A , its method A.match() is required to be passed an instance of Head class as shown on line 256 of the file struct_query.py. And according to the code inside the match() function, we can infer that the passed argument should be a token object. This conflict causes that I can't reproduce your code successfully. Maybe it's because I misunderstood some parts of your code. So could you please briefly explain to me how to change it so that it can run correctly? Thank you very much.
