重定向 301 和动态搜索页面生成

Question

I did some redirects 301 from my old domain to a new domain on new host. It works well, but I'm having a lot of 404's on google webmasters generated by dynamic search pages. Eg: www.newdomain.com/store/catalogsearch/result/index/?cat=60&dir=desc&limit=15&mod‌​e=grid&order=price&p=2&q=makita. But, I think this was crawled in the old domain, because of the searched words and are redirecting now to the new domain. Is there some generic rule to redirect all the others dynamic generated searchs to a specific page like home page on new domain without drop my ranking on google? On my new domain, dynamic search pages have been blocked in robots.txt. Is this way enough to not be crawled again? This is part of my redirect:

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*(default|index)\.(html|php|htm)\ HTTP/ [NC]
RewriteRule ^(([^/]+/)*)(default|main|index)\.(html|php|htm)$ http://www.newdomain.com/$1 [R=301,NC]
RewriteRule ^store/?$ http://www.newdomain.com [L,NC,R=301]
RewriteRule ^store/folder/?$ http://www.newdomain.com.br/otherfolder/another-folder/ [L,NC,R=301]
RewriteRule ^store/folder1/folder2/?$ http://www.newdomain.com/folder-3/folder-4 [L,NC,R=301]
...
RewriteCond %{HTTP_HOST} ^(www\.)?olddomain\.com$ [NC]
RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=301,NE,L]

Thanks in advance for your help.

ok insert this rule just below RewriteEngine On to redirect these dynamic URLs to home page of new domain:

RewriteCond %{THE_REQUEST} /store/catalogsearch/result/index/ [NC]
RewriteRule ^ http://www.newdomain.com/? [L,R=301]
