The Search capability finds passages in the data sources selected for an Agent and supplies relevant material to its response. It uses meaning and context, not only exact keyword matches. The Agent can search only sources and locations that have been made available to it. In Agent Builder, select the relevant connected sources, folders, websites, channels, or other locations offered by the workspace. Narrow the selection to the task. A focused source set makes results easier to interpret and can reduce unrelated matches. The underlying source must be connected and available in an appropriate Space.

​
Filter by labels

Where a source supports labels, use them to narrow the searchable documents. A must-have rule includes a document only when it has at least one required label. A must-not-have rule excludes a document if it has any excluded label. If in-conversation label filtering is available, the Agent can use exact label values from the request; spell the label exactly as it is stored.
Removing and re-adding a knowledge configuration can discard its existing must-have and must-not-have label filters. Test the change on a duplicated Agent first, or record the filters so they can be restored.

What semantic search does

For a question such as “What should I prepare for parental leave?”, semantic search can find passages about leave policy even when those passages do not use the exact wording of the question. The Agent then uses the retrieved passages with the question to draft a response and link back to sources when available. Search returns relevant material; it does not guarantee that every matching file or row was examined.

​
Filesystem-style navigation

Agents can also browse supported data sources like a file system: list folders, inspect directory structure, and open a specific file by path. This complements semantic search when folder organization carries meaning or a complete document is required. It may use additional tool calls and take longer. For SharePoint Content search, folder and path navigation is enabled by default for newly created knowledge configurations. Older configurations may need to be removed and re-added to receive this capability. Record existing label filters before doing so because re-adding the configuration does not preserve them. Use Search for questions about meaning, policy, or context in connected documents. For exact totals or calculations across structured rows, use Table queries.
