Does adding a Firestore index cause a read operation for every existing document?

If I add a new Firestore index to a database that already contains 100 documents will I be charged 100 reads for the index operation? I'm assuming it needs to scan all or at least a portion of the existing docs in order to index them.

This is a very similar question but I can't tell if it's referring to the ongoing cost of an index rather than the creation of one.

No. As Puff wrote very clearly:

The only cost for indexes is their storage cost

You will only be charged for the storage of them.
