Lucene (inverted index) is the underlying store. The maximum number of
documents that can be stored in it varies by hardware. You can scale ES out
horizontally with many nodes/servers if needed.

Each document can be pretty big. Some of mine are in tens of megabyte
dumps from pdf files. Examples:
https://commons.wikimedia.org/w/index.php?title=Special%3ASearch&profile=default&search="mens+rea"~0&fulltext=Search&srbackend=CirrusSearch
Most of those matches are from text extracted from the pdf files. Many of
those files are mostly text so the 10MB pdf turns into 8MB of text or
something.
