I am using nginx 1.14.0 on Ubuntu.

I want anyone coming to https://www.example.com/blog/authors/ should always redirected to https://www.example.com/blog which is working fine, but if anyone comes through https://www.example.com/blog/authors/?hello (with question mark) is being forwarded to https://www.example.com/blog/?hello

Why is it doing like this? and how can I correct my nginx configuration settings so even if anyone types in anything with question mark '?' to https://www.example.com/blog/authors/?hello should always forwarded to https://www.example.com/blog/ as well.

This is my redirect rule

# Redirects to handle all of the URL patterns from the old site
    rewrite ^/blog/authors/$ /blog/$1 permanent;

And, following is my complete nginx config block file

    server {
        listen 80;
        listen 443 ssl;
        server_name example.com www.example.com;
        access_log /var/log/nginx/example.com.access.log;

        ssl_certificate      /etc/nginx/ssl/example.com.crt;
        ssl_certificate_key  /etc/nginx/ssl/example.com.key;
        ssl_protocols        TLSv1 TLSv1.1 TLSv1.2;

        location = /favicon.ico { access_log off; log_not_found off; }

        location /static/ {
                root /my/server/site/path;
        }

        location / {
                include proxy_params;
                proxy_pass http://unix:/my/server/site/path/site.sock;

        }

        # Redirects to handle all of the URL patterns from the old site
            rewrite ^/blog/authors/$ /blog/$1 permanent; 
}

I have seen this answer to other question https://stackoverflow.com/questions/44782411/nginx-rewrite-question-mark but not sure exactly where do I need to make appropriate changes?

Why is it doing like this?

The official answer is at https://nginx.org/r/rewrite . Here's the direct quote from the above URL...

If a replacement string includes the new request arguments, the previous request arguments are appended after them. If this is undesired, putting a question mark at the end of a replacement string avoids having them appended

So the correct statement would be...

rewrite ^/blog/authors/$ /blog/? permanent;

or

rewrite ^/blog/authors/$ /blog? permanent;

... depending on if you'd like the trailing slash or not.

Only if we have a regular expression, rewrite is needed. All other redirects can be done using return statement that is faster due to lack of evaluation of regular expression.

For your use-case, my existing answer for a similar question would work. Here's the complete answer (for redirecting without query strings), though...

location /blog/authors {
    return 301 /blog;
}

Here's the complete server block...

server {
    listen 80;
    listen 443 ssl;

    server_name example.com www.example.com;

    root /my/server/site/path; # this line is needed to the location blocked added for redirection.

    access_log /var/log/nginx/example.com.access.log;

    ssl_certificate      /etc/nginx/ssl/example.com.crt;
    ssl_certificate_key  /etc/nginx/ssl/example.com.key;
    ssl_protocols        TLSv1 TLSv1.1 TLSv1.2;

    location = /favicon.ico { access_log off; log_not_found off; }

    location /static/ {
            root /my/server/site/path;
    }

    location / {
            include proxy_params;
            proxy_pass http://unix:/my/server/site/path/site.sock;
    }

    # Redirects to handle all of the URL patterns from the old site
    location /blog/authors {
        return 301 /blog;
    }
}

I hope that clarifies and helps.
