mod rewrite - how to write a rule query_string RewriteEngine -

need of such http://example.net/tags/index.php?tag=anytag, create such http://example.net/tags/anytag doing

rewriteengine on rewritecond %{query_string} ^tag=(.*)$ [nc] rewriterule ^tags/index.php$ /tags/$1 [nc,l,r=301]

not working

maybe want other way round

rewriterule ^/tags/(.*)$ /tags/index.php?tag=$1

rewritecond test string query_string used, when input contains query string. if want rewrite url url, append desired query string target url.
