Thanks for the feedback Sébastien! 1. Are you adding documents through the API with URLs? URL parsing is only supported through the UI right now, through the API it will just add that url as the metadata. 2. Will add md support soon! 3/4. We are working on ways to give more configuration to how the context is formatted like you mentioned, keep an eye out for updates! 5. The response from the completion API should return a "search_results" array which includes the chunks and other columns/metadata/images. If the array is empty there may be something wrong in the search config, happy to hop on a call some time or help in our Discord

Hope this helps!
