Удаление индекса в curl

Здравствуйте, настраиваю глобальный поиск, хочу удалить индексы:
http://айпи:81/sites/sales/search
Пробовал вот так:
curl -XDELETE http://айпи:81/sites/sales/search-*/
Но потом при curl -v -X POST -d '{"templateName": "default.json"}' -H "Content-Type: application/json" http://айпи:81/sites/sales/search
Как правильно удалить ранее созданные индексы?
Выдает ошибку:
