Short answer
No, you cannot duplicate a Project in AskTuring at this time.
Full explanation
AskTuring does not currently offer a feature to copy or duplicate a Project. If you need a similar Index with the same documents, you will need to create a new Project and re-upload the files manually.
This ensures that each Project is intentionally built and clearly documented from the start. The ability to duplicate a Project may be considered for future versions based on demand.
