（Wordpress）.htaccess选择性重定向

Question

I want to redirect the home of my old site to the home of my new site, while I want every subpage to redirect to the page search of the new site. Briefly:

www.oldsite.it --> http://newsite.it

and

www.oldsite.it/whatever --> http://newsite.it/search?q=whatever

I want the conditions to live both and strictly. I achieved to let them work but separately. Here's my code:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} oldsite\.it/$ 
RewriteRule ^(.*)$ http://newsite.it/search?q=$1 [R=301,L]

RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]
</IfModule>

How can I make them work? Thanks

You need 2 conditional rules here to redirect the old homepage and old urls to the new location ,try :

RewriteEngine On
RewriteBase /
#1)redirect "oldsite.it" to "newsite.it#
RewriteCond %{HTTP_HOST} ^(www\.)?oldsite\.it$ 
RewriteRule ^$ http://newsite.it [NC,L,R]    
#2)redirect "oldsite.it/foobar" to "newsite.it/search?q=foobar#
RewriteCond %{HTTP_HOST} ^(www\.)?oldsite\.it$ 
RewriteRule ^(.+)$ http://newsite.it/search?q=$1 [QSA,NC,R,L]

Clear your browser's cache before testing these rules.

To make the redirect permanent ,change R to R=301 in both rules when you are sure the rules are working.
