How to replace part of the address?

Question

htaccess

Hey!
How to replace part of url with 301?

site.ru?param1=text1¶m2=text2
to
site.ru?param2=text2

Moreover, the param1 part to be replaced can be both at the end and at the beginning of the get request, and it can also be different text1

I try unsuccessfully to do so. Works only on the main page of the site, does not work on internal pages

RewriteCond %{QUERY_STRING} ^(.*)param1=text1+(.*)$ [NC]
RewriteRule ^(.*)$ /$1?%1%2 [R=301,L]

Answer 1

RewriteCond %{QUERY_STRING} ^(|.*?&)param1=[^&]*&?(.*)
RewriteRule .* /$0?%1%2 [R=301,L]
