# v3 Change Summary

**Announcing Version 3 of Our API: Improved Search Results, New Filters, and Sorting**

Version 3 of our API introduces several large enhancements designed to deliver more relevant search results, along with new sorting capabilities. Here’s a summary of the key updates:

* **Semantic Search**:
  * Queries will now be run using semantic search — not pure text matching.
  * Semantic search means that instead of just matching exact keywords, the search engine understands the intent behind your query
    * For example, if you search for “latest updates on U.S. economic policy changes,” a semantic search engine will interpret that you're interested in news about fiscal, trade, or monetary policy, even if those specific terms aren't used in every article. It might return articles on government budget changes, regulatory reforms, or related market reactions—all because it recognizes that these topics are contextually related to your original query.
* **Key Phrases**
  * You can further refine semantic results using a parameter called "Key Phrases"
  * Key phrases enables you to use formulas and text, such as `('the fed' or 'federal reserve') and ('interest rates' or 'rates')` to further refine your results
* **Sort Order**
  * Users can now sort results based on relevance or date published

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://athena-10.gitbook.io/athena-api/v3-change-summary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
