pattern_n = page.search(r"\n")
*** ValueError: min() arg is an empty sequence
pattern_n = page.search(r"\s")

Hi @kathimohan. This is a really interesting question, and thank you for identifying this bug. I'm working on a fix for the error, which occurs because there is no internal PDF representation of a "newline"; we just perceive newlines based on the distances between lines of text. I spent some time today trying to derive the implicit "position" of the newlines, but nothing felt quite right. So, for now, searching for newlines will just return a blank result set.

I'm also working on some functionality related to your question here, which will provide a more convenient way to identify where newlines are: #852

As of v0.9.0, pdfplumber now returns an empty list (instead of throwing an error) when searching for whitespace or newline-only patterns.
