| This module is responsible for the VectorDB API. It currently supports: | |
| * DELETE api/v1/clear | |
| - Clears the whole DB. | |
| * POST api/v1/add | |
| - Add some corpus to the DB. You can also specify metadata to be added alongside it. | |
| * POST api/v1/delete | |
| - Delete specific records with given metadata. | |
| * POST api/v1/get | |
| - Get results from chromaDB. | |
