# Understanding synonym relationships ✨With the **Smart Product Filter & Search** app, you can improve your store's search results by using **Synonyms** — different words that mean the same thing. But did you know you can control *how* these synonyms behave using two types of relationships? Let’s break them down. *** ### 🔹**Inferred** In the **Inferred** relationship, the app will only match results from one direction.

#### Example: If you define: ``` T-shirt → Shirt ``` Then: * A search for **T-shirt** will show results for **Shirt** * But a search for **Shirt** will NOT show results for **T-shirt** ✅ Use this when you want one keyword to include others in the results, but not the other way around. *** ### 🔹**Equivalence** In the **Equivalence** relationship, the app will match both directions.

#### 💡Example: If you define: ``` T-shirt ↔ Shirt ``` Then: * A search for **T-shirt** will show results for **Shirt** * A search for **Shirt** will also show results for **T-shirt** ✅ Use this when all the terms should always return the same set of products. *** ### 🧠 Tips * Use **Inferred** if you want to direct traffic from general terms to more specific ones (or vice versa). * Use **Equivalence** when all terms mean the same thing and should return identical results. * Keep your synonym groups clean and relevant to avoid confusing search results. *** ### 💬 Need Help?
