RAG and Search

Search school material across all your applications

Before you begin

Availability depends on your school's enabled tools, provider setup, and account permissions. These settings are managed in the web workspace. A class policy may restrict a feature described here. Some options require a separately licensed feature. The presence of a guide does not unlock that feature.

One of Nexus's most standout features is the ability to enrich the LLM's general world knowledge with context unique to your team. Nexus uses Connectors to index knowledge from your team's applications to build an understanding of the documents, people, and concepts within your school.

Documents, metadata, and access permissions are all kept up to date in near real time.

Search UI#

On the top left of the page, you can select the mode of the UI. Replace "Auto" with "Search" to always go into this view.

Nexus's context retrieval respects user level permissions which is only configurable via the Enterprise Edition.

Nexus's knowledge connectivity can be used via both the Search and Chat interface. The Search interface provides a better view of documents and is better for quickly accessing documents when the intent is not to get an answer.

Users do not need to explicitly select this mode. when a query is classified by Nexus as a document search, it will automatically go into this UI experience.

Filters#

The Search UI also provides more advanced filtering options:

The top bar allows users to filter by time ranges (date range / time offset), authors, and tags (e.g. Folder: Engineering).

The side filters allow users to filter by the source type of the documents.

Chat UI#

Context from your applications are also available in the Chat UI and to Nexus Agents. Deep Research mode is also a Chat UI feature.
