Exercise 2: A Deleted Page — Why Date Filtering Doesn't Help, and What Does — Possible Solution
====================================================================

WHY searchtech1-5's DATE FILTERING CAN'T SOLVE THIS
------------------------------
Per this chapter's own comparison table, date filtering "filters many
search results by when they were published" - it operates on results
that currently exist in the search index. A page that has been deleted
entirely no longer has any content for a search engine to index or
return in the first place, regardless of what date range is applied.
Date filtering narrows down among existing candidates; it has no
mechanism for recovering something that no candidate result currently
represents at all.

THE ACTUAL PROBLEM, NAMED PRECISELY
------------------------------
Per this chapter, the real task here is "show me what this exact page
used to say" or "this page is gone - did anyone save it?" - recovering
one specific, already-known URL's own historical content, not finding
something recent among many results. This is a fundamentally different
kind of question than anything Chapter 5's date filtering was built to
answer.

WHAT ACTUALLY HELPS: THE WAYBACK MACHINE
------------------------------
Per this chapter, entering the page's URL at web.archive.org surfaces
a calendar-style timeline of every snapshot that page has, if any
exist - allowing the exact archived version from a specific date to be
opened even though the live page itself is gone. This directly matches
the chapter's own named use case of "confirming what a now-deleted
blog post originally said."

THE HONEST LIMIT ON THIS SOLUTION
------------------------------
Per this chapter's own warning, this only works if the page happened
to be archived before it was deleted - not every page has ever been
archived, so the Wayback Machine is the right tool to try, but not a
guaranteed recovery method.

WHY THIS WORKS AS AN ANSWER
------------------------------
It explains precisely why date filtering is the wrong category of tool
for this problem (it works on existing search results, not deleted
content), correctly identifies the Wayback Machine as the tool built
specifically for this exact scenario, and includes the chapter's own
honest caveat that recovery isn't guaranteed rather than presenting it
as a certain fix.
