Short answer
You may. If your documents cover different topics, projects, or audiences, multiple Projects can keep your results cleaner and more relevant.
Full explanation
A Project in AskTuring is a self-contained set of documents. If you only work with one type of content or project, your initial Project, called your "Default Project," may be enough.
However, if your documents span different areas such as client-specific files, internal policies, and research, splitting them into separate Projects helps. This approach:
Prevents unrelated information from mixing into your answers
Makes it easier to manage who has access to what
Improves search accuracy by narrowing the scope for each query
Because each Project is isolated, your sensitive data stays separated by design.
Examples
One Project for training materials, another for compliance documents
One Project for each client or account you manage
One Project for marketing content, another for technical manuals
Why it matters
Multiple Projects give you more control over accuracy, privacy, and organization. They are especially useful if your work spans multiple topics or you need to keep information strictly separated.
