Доброго времени суток! Пытаюсь настроить редирект для повторяющегося get параметра. Например ссылка:

http://site.ru/katalog/CD11104/?s-price-min=10&s-price-max=50&s-configurator-1000=500&и еще несколько s-configurator-x=y?s-cat_id=100

Должна превратиться в ссылку

http://site.ru/katalog/CD11104/100/100-500/id configurator-значение/id configurator-значение/и тд/price-min/price-max/

Вот правила:

if ($query_string ~ "^s-price-min=(.*)&s-price-max=(.*)&s-configurator-(.*)=(.*)&s-cat_id=(.*)"){
set $cat_1 $1;
set $cat_2 $2;
set $cat_3 $3;
set $cat_4 $4;
set $cat_5 $5;
rewrite /katalog/([^\/]*)\/(.*) /katalog/$1/$cat_5/$cat_3-$cat_4/pmin$cat_1/pmax$cat_2/? permanent;
}

if ($query_string ~ "^s-price-min=(.*)&s-price-max=(.*)&s-configurator-(.*)=(.*)&s-configurator-(.*)=(.*)&s-cat_id=(.*)"){
set $cat_1 $1;
set $cat_2 $2;
set $cat_3 $3;
set $cat_4 $4;
set $cat_5 $5;
set $cat_6 $6;
set $cat_7 $7;
rewrite /katalog/([^\/]*)\/(.*) /katalog/$1/$cat_7/$cat_3-$cat_4/$cat_5-$cat_6/pmin$cat_1/pmax$cat_2/? permanent;
}

и тд.

rewrite ^/katalog/([^\/]*)\/([^\/]*)\/([^\/]*)-([^\/]*)\/([^\/]*)-([^\/]*)\/pmin(.*)/pmax(.*)/?$ /index.php?/katalog/$1/&s-price-min=$7&s-price-max=$8&s-configurator-$3=$4&s-configurator-$5=$6&s-cat_id=$2? break;


rewrite ^/katalog/([^\/]*)\/([^\/]*)\/([^\/]*)-([^\/]*)\/pmin(.*)/pmax(.*)/?$ /index.php?/katalog/$1/&s-price-min=$5&s-price-max=$6&s-configurator-$3=$4&s-cat_id=$2? break;

и тд.

Вроде все работает, но когда доходит до 13 параметра

if ($query_string ~ "^s-price-min=(.*)&s-price-max=(.*)&s-configurator-(.*)=(.*)&s-configurator-(.*)=(.*)&s-configurator-(.*)=(.*)&s-configurator-(?<n0>.*)=(?<n1>.*)&s-configurator-(?<n2>.*)=(?<n3>.*)&s-configurator-(?<n4>.*)=(?<n5>.*)&s-configurator-(?<n6>.*)=(?<n7>.*)&s-configurator-(?<n8>.*)=(?<n9>.*)&s-configurator-(?<a0>.*)=(?<a1>.*)&s-configurator-(?<a2>.*)=(?<a3>.*)&s-configurator-(?<a4>.*)=(?<a5>.*)&s-configurator-(?<a6>.*)=(?<a7>.*)&s-configurator-(?<a8>.*)=(?<a9>.*)&s-configurator-(?<b0>.*)=(?<b1>.*)&s-configurator-(?<b2>.*)=(?<b3>.*)&s-configurator-(?<b4>.*)=(?<b5>.*)&s-configurator-(?<b6>.*)=(?<b7>.*)&s-configurator-(?<b8>.*)=(?<b9>.*)&s-configurator-(?<c0>.*)=(?<c1>.*)&s-configurator-(?<c2>.*)=(?<c3>.*)&s-cat_id=(.*)"){
