+### Enhanced search parameters
+
+The `SearchNodes` tool supports filtering options for more targeted searches:
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `entityType` | string | Filter results by entity type (for example, `Incident`, `Service`, `Resource`) |
+| `includeNeighbors` | bool | Include connected nodes in the search results |
+
+**Example:**
+
+```text
+Search for all incidents related to "database timeout" and include connected resources
+```
+
+With `includeNeighbors: true`, the search returns not only matching incident nodes but also their connected:
+
+- Resources
+- Services
+- Related incidents
+- Linked documents
+
+This enables richer context during investigations by showing the full relationship graph around matching nodes.

 ## Quick start
 
 Begin by establishing foundational knowledge with user memories, and then expand to document storage and automated synchronization as your needs grow.

     The portal automatically validates, uploads, and indexes files.
 
+### Upload via agent tool
+
+The agent can upload documents directly to the knowledge base using the `UploadKnowledgeDocument` tool. This is useful when:
+
+- Capturing troubleshooting steps discovered during an investigation
+- Adding runbooks generated from incident resolutions
+- Programmatically adding documentation without UI access
+
+**Tool: UploadKnowledgeDocument**
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `fileName` | string | Yes | Filename with extension (for example, `runbook-database-issues.md`). Must be `.md` or `.txt`. |
+| `content` | string | Yes | Full document content in plain text or Markdown format. |
+| `triggerIndexing` | bool | No | Trigger immediate indexing (default: `true`). Set to `false` for batch uploads. |
+
+**Example usage:**
+
+Ask the agent:
+
+> "Save our troubleshooting steps for the database timeout issue to the knowledge base"
+
+The agent uses `UploadKnowledgeDocument` to:
+
+1. Create a document with appropriate filename
+1. Format the content in Markdown
+1. Upload to Azure Blob Storage
+1. Trigger indexing for immediate searchability
+
+**Constraints:**
+
+- Maximum file size: 16 MB
+- Supported extensions: `.md`, `.txt` only
+- If a document with the same filename exists, it's overwritten
+
+**Error handling:**
+
+| Error | Resolution |
+|-------|------------|
+| "Agent memory is disabled" | Enable agent memory in configuration |
+| "Invalid file extension" | Use `.md` or `.txt` extension only |
+| "Document content exceeds maximum size" | Split large documents into smaller files |
+
