According to the Apache documentation, for $N value of N can only be 0-9. Therefore, trying to get $10 will not work. You may have to go through two stages of rewriting. So maybe you are using something like this:
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+/[^/]+/[^/]+)/?$ search.php?country=$1&state=$2&gender=$3&r_city=$4&r_mstatus=$5&r_religion=$6&r_ethnicity=$7&r_cast=$8&r_profession=$8&profession_and_education_and_sort=$9 [NC] RewriteCond %{REQUEST_FILENAME} ^search\.php$ RewriteCond %{QUERY_STRING} ^(country=.*&state=.*&gender=.*&r_city=.*&r_mstatus=.*&r_religion=.*&r_ethnicity=.*&r_cast=.*)&profession_and_education_and_sort=([^/]+)/([^/]+)/([^/]+) RewriteCond ^search\.php$ search.php?%1&r_profession=%2&r_education=%3&sort_by=%4 [NC,L]
