Explanation:

Why Synonyms Enable Unified Search Results
In Salesforce B2C Commerce, when a merchant wants different customer search terms to return the same product results, they use the Synonym Dictionary under the search configuration.

🔄 Example Use Case
For the terms:
Bag
Purse
Pocketbook
Tote

You want customers using any of these to get identical search results. This is a textbook case for defining a synonym group.

✅ Synonyms
Synonyms allow the search index to treat multiple terms as equivalent.
You define a group like:
bag = purse = pocketbook = tote
No matter which term the shopper uses, they'll receive results mapped to all members of the synonym group.

❌ Why Hypernyms and Hyponyms Are Incorrect

Hypernyms
Generalizations (e.g. "accessory" is a hypernym for "bag") Would broaden the result scope — not helpful if you want consistent, targeted results
Hyponyms
Sub-categories (e.g. "clutch" or "satchel" under "bag") Too specific — would lead to inconsistent results if only one hyponym is matched
