Release Notes
Enhanced Multi-Source Queries
Attach up to five knowledge sources in a single query to get high-quality responses.
What’s New
You can now attach up to five knowledge sources to a single query, up from the previous limit of two. This applies to new threads created in the Harvey web app as well as the Harvey Word add-in.
- Combine multiple knowledge sources with web search in the same query
- Set granular filters for each source to keep results scoped to the right context
As part of this change, citations are now grouped by knowledge source for easier navigation and verification.
Why It Matters
Legal research often spans more than two authorities. Before this update, comparing several jurisdictions meant running separate queries and piecing the answers together by hand. Now one query can cover the full scope of the question, whether that's several jurisdictions, a cross-border comparison, or a mix of sources like a regulator, a statute database, and web search.
How To Use
- Start a new thread and draft your query.
- Select Sources and add up to five knowledge sources.
- Submit your query.
- Review the response, organized by source, with citations back to each one
Tips for best results:
- Name each source's role in your prompt and state the jurisdiction explicitly.
- Select only the sources the question needs (usually three to four).
- Use web search to supplement primary law, not replace it.

- Knowledge Sources: France, Singapore, Switzerland, US, US Case Law
- EU-focused: When does acquiring a UK semiconductor supplier require NSIA notification, and could EU investment screening also apply? Ground your answer in the statutory triggers, leading commentary, and recent guidance.
- Knowledge Sources: England & Wales, FromCounsel, European Union, Web
FAQs
Q: Does this change the number of vaults or connectors that can be attached to a single query?
No. This change only expands the number of knowledge sources that are included in a query.
Q: Does this update change workspace permissions on knowledge sources or web search?
No. This change only updates the upper limit of sources that you can attach to a single query. Admins can still freely control which knowledge sources are available in their workspace in the Command Center under Configurations → Knowledge.
Additionally, no permissions or settings changes are impacted if workspaces have set up additional limitations or guidelines when using web search.
Q: Does this change update the number of sources that can be used concurrently with Ask LexisNexis?
No. Ask LexisNexis cannot be combined with other sources at this time.
