使用mod_rewrite时,字符串在&符号后截止

If I have a variable with an ampersand, and try to echo the variable in php, the string is cut off at the ampersand when using mod rewrite URL's.

The variable is search & search

When using:

page.php?s=search+%26+search

I can echo the complete variable. search & search

When using rewritten URL's:

page/search+%26+search/

I echo the variable and it prints search

What needs to be added to htaccess to fix this?

current htaccess:

RewriteCond %{THE_REQUEST} /page\s=([^&\s]+) [NC]
RewriteRule ^ page/%1? [L,R=302,NE]

RewriteRule ^page/([^/]+)/?$ page.php?s=$1 [L,QSA]
