'Delayed search for information about specific search items.
Typically, this will be used when certain information such as
formats, drm status, cover url are not part of the main search
results and the information is on another web page.
Using this function allows for the main information (title, author)
to be displayed in the search results while other information can
take extra time to load. Splitting retrieving data that takes longer
to load into a separate function will give the illusion of the search
being faster.
:param search_result: A search result that need details set.
:param timeout: The maximum amount of time in seconds to spend downloading details.
:return: True if the search_result was modified otherwise False'

def get_details(self, search_result, timeout=60):

    return False
