My clients wordpress websites is serving many 404 requests. After checking I could see that the 404 URLs are like 

/wp-content/uploads/2015/8/a.png&_nc_hash=ASsvdeeknbhs

and it throws 404 error. But if we add a '?' after that filename, it will show the content. the working url was like 

/wp-content/uploads/2015/8/a.png?&_nc_hash=ASsvdeeknbhs

How to set this redirection in nginx ? Please help me to achieve above redirection. Any good recommendations would be appreciated.

    You should find out which part of the website generates these invalid URLs in the first place. Adding a redirect to fix this issue makes it simply more complicated. – Tero Kilkanen Dec 20 '16 at 02:53

I have been looking for a temporary/immediate fix. The following redirection rules helped me.

rewrite ^(.*)&_nc_eui2(.*)$ $1?&_nc_eui2$2 permanent;
rewrite ^(.*)&_nc_hash(.*)$ $1?&_nc_hash$2 permanent;
rewrite ^(.*)word(.*)$ $1newwordOLDWORD$2 permanent;

I hope it would help someone. :)
