With Synerise AI search, you can effectively control how your search engine processes queries. By using synonyms, you can increase the reach of your products and make sure that customers always find what they are looking for.

This use case describes the process of creating synonyms for a headphones query. 

## Prerequisites
---
- An item feed must be provided.
- Enable [The Search Engine](/docs/ai-hub/ai-search/introduction-to-ai-search) for your workspace and create an [index](/docs/ai-hub/ai-search/create-index).
- [Implement AI search](https://developers.synerise.com/AISearch/AISearch.html) in any of your channels (mobile app, website etc.)

## Add synonyms
---
In this use case, you add synonyms to a set of words: **headphones, headsets, earphones** so that when a user types any of these words into a search engine, they are all treated as synonyms of each other and will produce relevant search results.

1. Go to <img src="/api/docs/image/54176ad07f146575310749eba44b7c2f42c1b327/icons/ai-hub-icon.svg" alt="AI Hub icon" class="icon" > **AI Hub > Indexes**.
2. Select an index from the list.
3. Click the **Synonyms** tab.
4. Click **Add synonym > Add synonym**. 
5. From the dropdown list, select **Two ways**.
5. In the **Synonyms** field, enter: `headphones, headsets, earphones` 
    In this configuration, each word in the list a synonym of the other words.
6. Confirm by clicking **Add**.
