Demo app using Realm as a Vector Store

This is a modified version of mongodb/template-app-kotlin-todo that showcases a local semantic search and a Retrieval-Augmented Generation with a GenAI

Note: This is based on a custom version of Realm Kotlin SDK that uses a POC of KNN search.

The Demo uses 4 recent articles from https://www.mongodb.com/developer/news/ that are not yet indexed by the GPT mode gpt-3.5-turbo at the time of this demo

Then offer two search modes:

Semantic Search:

We can search local articles (The question is embedded using text-embedding-ada-002 but the KNN search is done locally)

Retrieval-Augmented Generation Search:

The GPT search brings outdated answers (Laravel 10). Whereas the RAG search uses local articles for a more up-to-date answer
