REST GET /api/content/[id]/child/page not returned immediately

I am adding a lot of confluence pages into a space via REST API. So there is a heavy load to the lucene Indexer.

Querying by GET /api/content/{id}/child/page is not returning all content immediately.

When I try some minutes later the query returns the content.

Is there an REST API where the lucence index is not used and the REST Endpoint reads it directly form database?
The page tree macro an the left side is finding that item - so there must be a other opportunity.

Thanks in advance!
