How SharePoint generate automatic indexes

Question

I have created a custom SharePoint online list, and I did couple of sorts inside my list views, where all the fields i made sort on them get added as automatic indexes inside the list.

So will automatic indexing consider the sort we do inside power apps, power automate, SharePoint rest api and graph Api? or it only consider the sort we do inside the list views?

Thanks

Hi @john john Pter ,

When you sort a column within a list view, SharePoint automatically creates an index for that column. This index helps optimize filtering and sorting operations within that view.

The automatic index creation is limited to lists and libraries with fewer than 20,000 items. If your list has more than 20,000 items, you won’t get automatic indexing when sorting within a view.

Unfortunately, automatic indexing doesn’t extend to these scenarios. When you perform sorting or filtering using Power Apps, Power Automate (Flow), REST API, or Graph API, SharePoint won’t automatically create indexes.
