wordpress - 301 redirect with query string - woocommerce products -

here problem i've stalled days. setup wordpress woocommerce installed. permalinks structure works great, need redirect old urls new ones.

old url structure looks this: http://domain.tld/?product=bla-bla

but need them redirect this: http://domain.tld/product/bla-bla

*bla-bla dynamic part.

the rule in .htaccess i've made:

rewritecond %{query_string} ^product=(.*)$ [nc] rewriterule ^$ /product/%1 [nc,l,r=301] 

but result partially wrong: http://domain.tld/product/bla-bla?product=bla-bla

the contents of .htaccess:

rewriteengine on rewritebase / rewriterule ^index\.php$ - [l] rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule . /index.php [l]  rewritecond %{query_string} ^product=(.*)$ [nc] rewriterule ^$ /product/%1 [nc,l,r=301] 

i appreciate help!

have way:

rewriteengine on rewritebase /  rewritecond %{query_string} ^product=(.*)$ [nc] rewriterule ^$ /product/%1? [nc,l,r=301]  rewriterule ^index\.php$ - [l] rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule . /index.php [l] 

? @ end of target strip off query string original url.
