# Indexing Status

When documents are added to a knowledge base, they go through a processing pipeline before they become searchable. The indexing status lets you monitor this progress.

## Processing states

Each document progresses through these states:

| State          | Description                                                   |
| -------------- | ------------------------------------------------------------- |
| **Uploaded**   | File has been received and stored, awaiting processing        |
| **Processing** | Content is being extracted, split into chunks, and embedded   |
| **Indexed**    | Successfully processed — the document is searchable by agents |
| **Failed**     | Processing encountered an error (see troubleshooting below)   |

## Monitoring progress

From the knowledge base detail page, you can see:

* **Overall progress** — A summary of how many documents are indexed vs. pending
* **Per-document status** — The current state of each individual document
* **Datasource sync status** — For connected sources like SharePoint, the last sync time and result

## Processing time

Processing time depends on several factors:

* **File size** — Larger files take longer to process
* **File type** — PDFs with complex layouts or scanned content take longer than plain text
* **Queue depth** — If many documents are being processed simultaneously, individual documents may wait in the queue
* **Content complexity** — Documents with tables, images, or mixed formatting require more processing

Typical processing times:

| Scenario                  | Expected time |
| ------------------------- | ------------- |
| Small text file (\< 1 MB) | Seconds       |
| Standard PDF (1–10 MB)    | 10–60 seconds |
| Large document (10–50 MB) | 1–5 minutes   |
| Bulk upload (100+ files)  | 10–30 minutes |

## Troubleshooting failed documents

If a document shows **Failed** status:

* **Unsupported format** — Ensure the file is in a supported format (PDF, DOCX, XLSX, TXT, PPTX, CSV)
* **Corrupted file** — Try opening the file locally to verify it's not corrupted
* **File too large** — Check if the file exceeds your plan's size limits
* **Extraction error** — Some heavily formatted or encrypted PDFs may fail. Try converting to a simpler format.

You can retry a failed document by deleting it and re-uploading.
