SharePoint does not provide a way to crawl documents by date range, so all documents will need to be crawled regardless of any date range requirement, and then filtered.
So at this point it is important to ask the client if their requirement's purpose is to save crawling load on the server, because if it is, you won't get much savings. But if the client wants this feature for other reasons, we can support it with some work.
Please open a ticket if you find that the client has a legitimate reason for this requirement.
