Attach only the databases a question needs. Searching many databases at once returns more near-matches and weaker answers. A chat can search up to ten sources at once, counting the current project and **Attach entire SharePoint** under **Integrations** in the picker.
## Check the answer's sources
An answer drawn from a database is cited like any other. Those citations are how you check it, so it is worth knowing what each one gives you.
Access to a database is separate from access to any project. An unshared database is visible only to its owner — the team's Owner and Admins cannot see it either.
So before a colleague leaves the firm, check that their databases have been shared.
## Delete a database
Deleting a database removes it for everyone it was shared with. What happens to the documents depends on where else they live.
**Ask Libra** is the one to reach for when you are already browsing a database and a question occurs to you. It opens a new chat with that database attached and your question already sent.
