is there any way to get all document count in any collection , currently its not showing more then

There is currently an issue on GitHub discussing adding aggregate functions to Appwrite, which would include getting the document count in a collection. You can show your support for this feature by giving it a thumbs up on the GitHub page (link provided). In the meantime, if you need a running total of all documents, you can set up a new collection and create a function with a trigger on document creation to keep track of the total count there.
