**Domain Datasets:**
- `academic` is the `jamescalam/ai-arxiv2` dataset, contains a selection of chunked papers from Arxiv on the topic of AI/ML. Creates the `AI_Arxiv` collection in the Weaviate instance
- `finance` is the `AgamiAI/Indian-Income-Tax-Returns` dataset, fully synthetic Indian Income Tax Return forms. Creates the `Income_Tax_Returns` collection in the Weaviate instance
- `ecommerce` is the `pkghf/ecom-product-catalog` dataset, containing structured e-commerce product information including product details, pricing, categorization. Creates the `Product_Catalog` collection in the Weaviate instance
- `medical` is the `Amod/hair_medical_sit`, containing information about common hair related diseases. Creates the `Hair_Medical` collection in the Weaviate instance
