 The sample uses a local Vector Database, called [Vectra](https://github.com/Stevenic/vectra), and [Semantic Search](https://en.wikipedia.org/wiki/Semantic_search) to find the most relevant information to include in the prompt for the users input. The index can be found in `./index/teams-ai` and includes all of the projects Getting Started docs and the source code for the Teams AI Library.

+In addition, the sample illustrates our streaming feature. This is enabled via using our `DefaultAugmentation` class, and by setting `stream: true` in the OpenAIModel declaration. The informative message can be set in the `ActionPlanner` declaration via the `startStreamingMessage` config. Custom logic is available through the `StreamingResponse` class.
