Send an email with attachments to the configured email account 2. DocuElevate will poll the mailbox at the configured interval 3. Attachments will be automatically downloaded and processed 4. No further action is required ## Managing Documents The **Files** page provides access to all processed documents: 1. Navigate to the **Files** page 2. Use the search box to find specific documents by filename, or the full-text search bar to search document content, metadata, and tags 3. Click on any file to view its details 4. Sort the list by any column by clicking on the column header > **Tip:** When documents are being processed, a blue banner appears at the top of the Files page showing how many items are queued or currently processing. Files will appear in the list once their processing completes. Admins can click "View Queue" in the banner to open the Queue Monitor dashboard. ## Queue Monitor (Admin) The **Queue Monitor** dashboard provides real-time visibility into the document processing pipeline. It is available to admin users under **Admin → Queue Monitor** in the navigation bar. The dashboard shows: - **Queued Tasks** — number of tasks waiting in Redis-backed Celery queues - **Active Tasks** — tasks currently being executed by Celery workers - **Files Processing** — files with at least one in-progress processing step - **Workers Online** — number of connected Celery worker processes - **Redis Queues** — per-queue breakdown of pending task counts - **Processing Pipeline** — database-level summary of file states (completed, processing, pending, failed) - **Recently Processing Files** — the most recent files being actively processed, with links to their detail pages The dashboard auto-refreshes every 10 seconds. ## Searching Documents DocuElevate provides two ways to search your documents: ### Full-Text Search on the Files Page The **Files** page includes a full-text search bar (labelled "Full-Text Search") that searches across OCR-extracted text, AI metadata, tags, sender, recipient, and document type. Type at least 2 characters and results appear automatically below the search bar. ### Dedicated Search Page For a more focused content-finding experience, use the **Search** page accessible from the main navigation: 1. Navigate to the **Search** page 2. Type your query into the search box — results appear automatically as you type (or press Enter) 3. Use the **content-finding filters** to narrow results: - **Document Type** — e.g. Invoice, Contract - **Tags** — filter by a specific tag - **Sender** — filter by sender / absender - **Language** — filter by ISO language code (e.g. `de`, `en`) - **Text Quality** — filter by OCR text quality (High, Medium, Low, No text) - **Date From / Date To** — restrict results to a date range 4. Results are displayed in a Google-style format showing: - **Document title** (linked to the file detail page) - **Filename** - **Document type**, **sender**, and **tag** badges - **Content preview** with highlighted matching terms 5. Use pagination to browse through large result sets ### Saved Searches Both the **Files** and **Search** pages support **saved searches** — named filter presets you can create and reuse: 1. Apply your desired filters (and optionally a search query on the Search page) 2. Click **Save Current** in the saved searches bar 3. Enter a name for the saved search 4. Your saved search appears as a clickable tag — click it to instantly re-apply those filters 5. Click the **×** button next to a saved search to delete it On the **Search** page, saved searches store the full-text query (`q`) along with all active content-finding filters. On the **Files** page, saved searches store the file management filters (filename search, MIME type, status, etc.). The search page is also accessible via URL with a pre-filled query: `/search?q=invoice` ### File Detail View When you click on a file, you'll see a comprehensive detail view with the following sections: #### File Information This section displays metadata about the file: #### File Information This section displays metadata about the file: - File ID and original filename - File hash (SHA-256) - File size and MIME type - Creation timestamp - Original file path and status (shows if the immutable original is available) - Processed file path and status (shows if the final processed file is available) #### Extracted Metadata (GPT) If metadata has been extracted by GPT, this section displays structured information including: - **Document Type**: Classification (Invoice, Receipt, Contract, etc.) - **Suggested Filename**: AI-recommended filename based on content - **Document Date**: Extracted date from document - **Sender (Absender)**: Sender or issuing party information - **Recipient (Empfänger)**: Recipient information - **Amount (Betrag)**: Financial amounts (for invoices, receipts) - **Account Number**: Bank account information - **Tags**: Document categories and labels **Show JSON**: Click this button to toggle the full metadata in JSON format. This is useful for: - Viewing all extracted fields at once - Debugging metadata extraction issues - Copying metadata for external use - Understanding the complete data structure #### Document Previews View your documents with type-specific viewers: - **Original Document**: The immutable original file as first ingested, before any processing - **Processed Document**: The final file with embedded metadata **PDF Preview (pdf.js)**: - In-browser PDF rendering via pdf.js — no native browser PDF plugin required - Page navigation controls (previous / next) with page counter - High-quality canvas-based rendering that works consistently across browsers - Side-by-side comparison of original vs processed versions on the detail page **Image Preview (JPEG, PNG, TIFF, WebP)**: - In-browser image display with zoom and pan controls - Zoom in / out buttons and mouse-wheel zoom - Click-and-drag panning for large or zoomed images - Reset button to return to the original size - Zoom percentage indicator **Text File Preview**: - Syntax-highlighted display with line numbers - Monospace font for readable code and data - Copy-to-clipboard button for the full text content - Supports plain text, CSV, source code, and other text MIME types **View Extracted Text** buttons below each preview to see the full text content **Text Extraction Modals**: Click "View Extracted Text" to open a fullscreen modal showing: - Complete extracted text from OCR or PDF text layer - Dark-themed, scrollable display for easy reading - Copy-friendly pre-formatted text - Close by clicking the close button or clicking outside the modal **Note**: The original file is stored in an immutable archive (`workdir/original/`) and is never modified. The processed file is stored in `workdir/processed/` with the suggested filename and embedded metadata. #### Processing History View the complete processing history with a timeline showing: - Each processing step that was executed - Status of each step (success, failure, in progress, pending) - Error messages for failed steps - Timestamps for each operation **Retry Processing**: If a file's processing has failed, you can use the "Retry Processing" button to reprocess the entire file. This is useful when: - External API services (like the configured AI provider) had temporary issues - Network connectivity was lost during processing - Configuration has been updated and you want to reprocess with new settings **Force Cloud OCR**: For files with low-quality embedded text, you can use the "Reprocess with Cloud OCR" option to force high-quality Azure Document Intelligence OCR processing, even if the PDF already contains embedded text. This is useful when: - The embedded text quality is poor or contains errors - OCR accuracy needs to be improved - The embedded text is corrupted or garbled - You need the highest quality text extraction possible #### Process Flow Visualization The process flow visualization shows a visual representation of the document processing pipeline: - **Green indicators**: Successful stages - **Red indicators**: Failed stages with error messages - **Gray indicators**: Stages that were not executed (e.g., because a previous stage failed) This helps you understand: - Which processing path your document took (local text extraction vs. OCR) - Where exactly the processing failed - Which stages were skipped and why #### File Previews If your file is still available on disk, you can preview it directly in the browser: - **Original File**: The immutable original file as it was first ingested - **Processed File**: The file after metadata has been embedded (if processing completed) Both previews support: - In-browser PDF viewing with pdf.js (canvas-based, no browser plugin needed) - Image viewing with zoom/pan for JPEG, PNG, TIFF, and WebP - Text file viewing with line numbers for plain text, CSV, and source code - Side-by-side comparison of original and processed versions - Full text extraction viewing via modal overlays **Quick Preview from File List**: On the main Files page, each file row includes an eye icon button that opens a slide-out side panel with a quick preview. This lets you: - Preview PDFs, images, and text files without leaving the file list - Navigate PDF pages within the panel - Zoom and pan images - Open the full document view or download the file from the panel footer **View Extracted Text**: Each preview includes a button to view the complete extracted text in a fullscreen modal. When you click this button: - The system extracts text from the PDF file on-demand using pypdf - A loading indicator shows while extraction is in progress - The extracted text is displayed in a scrollable, copy-friendly format - The text is cached so subsequent views load instantly This is useful for: - Verifying OCR accuracy - Searching within document content - Copying text for external use - Reading documents without downloading them **Note**: The original file is stored in an immutable archive (`workdir/original/`) and is never modified. This ensures you always have access to the file exactly as it was uploaded, which is valuable for: - Auditing and compliance - Debugging processing issues - Reprocessing with improved algorithms ## Document Processing Features Depending on the system configuration, DocuElevate can perform: - **OCR** - Extract text from images and scanned PDFs - **Metadata Extraction** - Automatically identify document types, dates, and other key information - **PDF Conversion** - Convert various file formats to PDF - **Document Distribution** - Store documents in Dropbox, Nextcloud, or Paperless NGX ### Paperless-ngx Integration If Paperless-ngx is configured, DocuElevate can automatically upload processed documents and set custom fields with extracted metadata: 1. **Automatic Upload**: After processing, documents are automatically uploaded to Paperless-ngx 2. **Custom Fields Support**: DocuElevate can automatically populate custom fields in Paperless with extracted metadata 3. **Flexible Field Mapping**: Map any extracted metadata field to any custom field in Paperless #### Setting Up Custom Fields **Basic Setup (Single Field)**: ```bash # In your .env file PAPERLESS_CUSTOM_FIELD_ABSENDER=Absender ``` **Advanced Setup (Multiple Fields)**: ```bash # Map multiple metadata fields to Paperless custom fields PAPERLESS_CUSTOM_FIELDS_MAPPING='{"absender": "Sender", "empfaenger": "Recipient", "language": "Language", "correspondent": "Correspondent"}' ``` **Available Metadata Fields**: - `absender` - Sender/author - `empfaenger` - Recipient - `correspondent` - Issuing company (short name) - `language` - Document language (e.g., "de", "en") - `document_type` - Classification (Invoice, Contract, etc.) - `reference_number` - Invoice/order/reference number - `kommunikationsart` - Communication type - `kommunikationskategorie` - Communication category - And more... **Requirements**: - Create the custom fields in Paperless-ngx first (Settings → Custom Fields) - The field names in your configuration must exactly match the names in Paperless - Ensure `PAPERLESS_HOST` and `PAPERLESS_NGX_API_TOKEN` are configured **How It Works**: 1. DocuElevate extracts metadata from your documents using AI 2. The document is uploaded to Paperless-ngx 3. After successful upload, custom fields are automatically populated 4. You can view the populated fields in your Paperless-ngx document details ## API Access For programmatic access, DocuElevate provides a comprehensive REST API: 1.
