Exercise 1: Walking Through search1-10's Framework as a Real "Yes" Case — Possible Solution
====================================================================

WALKING THROUGH THE FIVE QUESTIONS
------------------------------
Per this chapter, applying search1-10's own framework directly to the
e-commerce scenario:

Question 1 (primary feature or secondary convenience?): "search IS
the storefront's own primary feature, not a secondary convenience" —
YES. For an e-commerce storefront, product search isn't a helper
feature bolted onto something else; it's a core part of how customers
actually find and buy products.

Question 2 (genuine need for horizontal distribution?): "the catalog
is genuinely large enough to benefit from real horizontal
distribution" — YES, per the scenario's own stated "genuinely large
product catalog."

Question 3 (faceted search/aggregation as a first-class requirement?):
"faceted filtering (category, brand, price) is a first-class,
heavily-used requirement for this storefront" — YES, matching the
exact e-commerce faceted-sidebar pattern search1-7's own chapter
demonstrated.

Question 4 (does relevance quality materially affect success?):
"relevance quality genuinely affects conversion and revenue" — YES,
since a shopper who can't find relevant products quickly is a shopper
likely to leave without buying.

Question 5 (team prepared to operate a separate system?): "the team is
prepared to operate a separate system and keep it synced with the real
product database" — assumed YES for this scenario.

WHY THIS IS A GENUINE "YES" CASE, COMPLEMENTING SEARCH1-10'S OWN "NO"
EXERCISES
------------------------------
Per this chapter, "unlike search1-10's own two exercise scenarios —
both genuine 'no' cases — this is a real, complete 'yes' case, closing
that chapter's own framework from the other direction." search1-10's
own Exercise 1 (a rarely-used internal wiki) and the chapter's own
worked-through internal-wiki example both resulted in every framework
question pointing AWAY from a dedicated search engine. This capstone
scenario is deliberately the mirror opposite — every single one of the
five questions genuinely resolves to "yes" for a real, legitimate
reason specific to e-commerce search. Together, the internal-wiki "no"
case and this capstone's own "yes" case demonstrate the framework
actually discriminating correctly between two genuinely different real
situations, rather than the framework only ever being exercised in one
direction.

WHY THIS WORKS AS AN ANSWER
------------------------------
It walks through each of the five framework questions individually
using the chapter's own stated reasoning for the e-commerce scenario,
and explicitly explains why pairing this "yes" case with search1-10's
own earlier "no" case demonstrates the framework's own real
discriminating power, rather than treating the capstone's own
conclusion as a foregone assumption.
