Why does 301 redirect with parameters not work?

Question

htaccess

RewriteCond %{QUERY_STRING} ^nomer=370$ [NC]
RewriteRule ^production\.php$ /? [R=301,L]

Should redirect /production.php?nomer=370 to the main page. I noticed that if you put index instead of production, then everything is OK, the redirect works.
What could be wrong?

Answer 1

In general, everything is written correctly, if you only have several get parameters, try to clarify like this

RewriteCond %{QUERY_STRING} (^|&)nomer\=370($|&)
RewriteRule ^production\.php$ /? [L,R=301]

But then again, you seem to be fine.
In what part of .htaccess is it usually not under CNC?
