Why is my google advanced search presenting this error?

Question

i'm currently developing the project 0 (search) for the cs50x Web Programming with Python and Javascript and in the Advanced Search, when i submit the input given, que google query goes like this: tri-colour rat terrier miniature OR OR OR standard "rat terrier" --rodent (the OR appear 3 times and the "-" twice). I currently have no idea what may be causing it, did someone algo have this problem?

Here's the html code i'm using:
