advanced分支获取不到es索引

[sshnuke3]

配置好后打开首页报错
{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index [products]","resource.type":"index_or_alias","resource.id":"products","index_uuid":"na","index":"products"}],"type":"index_not_found_exception","reason":"no such index [products]","resource.type":"index_or_alias","resource.id":"products","index_uuid":"na","index":"products"},"status":404}
应该怎么创建索引来着？
