Why doesn't 301 redirect work from page to page?

Question

htaccess

Tell me why the 301 redirect does not work and what needs to be done for this?
If the pages are static or a redirect from static to ?page=2 then it works, but when such conditions, then nothing happens at all. How to be?

RewriteCond %{REQUEST_URI} /mebel/komod-arlen-8?page=18$
RewriteRule ^(.*)$ https://******.ru/rossiya/komod-arlen-8?page=2 [ R=301,L]

Answer 1

GET parameters should be looked for in the %{QUERY_STRING} variable.

RewriteCond %{QUERY_STRING} (^|&)page=18($|&)
RewriteCond %{REQUEST_URI}  ^/mebel/komod-arlen-8$
RewriteRule ^(.*)$ https://site.ru/rossiya/komod-arlen-8?page=2 [R=301,L]

Or

RewriteCond %{QUERY_STRING} (^|&)page=18($|&)
RewriteRule ^mebel/komod-arlen-8$ https://site.ru/rossiya/komod-arlen-8?page=2 [R=301,L]
