This an Apache mod\_rewrite thing.

There’s no equivalent in Nginx. It uses a saner, more clear approach  
of a _single_ condition + rule in Apache terms.

Can be placed in a single rule:

rewrite /(._)((maps|test|install|addon|cron)/)(._)$ /$2$3 last;

This is just the condition, what’s the rule?

if ($request\_uri != index.php) {  
(…)  
}

Note that an if is in fact an implicit location, so the only safe  
thing to do inside is to return a status code or a rewrite with the  
‘last’ flag. Cf. [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/IfIsEvil)

and getting error not found

Error: Requested page was not found!  
Details: livesearch&q=kylie &type=web Action not found!  
Home

This is just the condition, what’s the rule?

if ($request\_uri != index.php) {  
(…)  
}

i think the rule is adding + request url if i dont put this command on  
htaccess apache automaticly adding %20 between words on the result page  
if i put this into htaccess its automaticly adding + between result  
words on result page

for instance

[http://www.mysite.com/search/web?search=katy+perry&type=web](http://www.mysite.com/search/web?search=katy+perry&type=web)  
with RewriteCond

[http://www.mysite.com/search/web?search=katy%20perry&type=web](http://www.mysite.com/search/web?search=katy%20perry&type=web)  
without RewriteCond

they both working btw

This should be translated from Yoda backward style to nginx forward  
style:

location = /index.php {  
…  
}

location / {  
…  
}
