What the data for this category looks like
Tender announcement data comes from public resource trading platforms and official government procurement release channels. Update rhythm adjusts dynamically with tender project releases. Core project updates are concentrated on workdays. Documents typically include fixed fields: project name, tender number, budget amount, bidder qualification requirements, bid deadline, bid opening location, and others. Budget amount uses RMB yuan or ten thousand yuan as units. Time fields follow standard datetime formats. Some documents include complete tender document attachments in PDF format, which contain project details and supplementary notes.
What constraints these characteristics impose on deployment and upgrade
Data sources are public official channels. Configure directional crawling or API synchronization rules to prevent invalid data from non-target data sources from entering the knowledge base. Documents contain fixed-format core fields. Enable structured field extraction configuration during deployment to ensure accurate extraction of key information such as budget amount and bid deadline. Update rhythm changes dynamically with projects. Configure incremental synchronization trigger logic to avoid duplicate storage and calculation from full synchronization. Some documents include PDF attachments. Deploy PDF parsing-compatible plugins to ensure attachment content can be fully indexed. During upgrades, adapt to format changes from various local official channels to prevent parsing failures caused by page structure adjustments.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Tender announcements and their attached PDF documents usually contain multi-page tables and long text. The conventional parsing duration must accommodate the processing cycle for such documents |
UPLOAD_FILE_MAX_SIZE | 500 MB | Some tender attachments include complete tender documents or engineering drawings. Support for uploading and parsing large files is required |
chunk_size | 800–1200 characters | Core content of tender announcements, such as bidder qualification requirements and project requirements, are mostly coherent long texts. This segment length preserves context integrity |
recall_top_k | Top 8–12 results | Relevant retrieval for tender announcements usually needs to cover associated announcements and supplementary notices for the same project. An appropriate number of recalled results ensures comprehensive information |
SYNC_INCREMENTAL_ENABLE | Enabled | Tender announcements are incrementally published data sources. Incremental synchronization avoids repeated processing of already stored historical announcements |
STRUCTURED_EXTRACT_FIELDS | Configured as ["project_name", "tender_number", "budget_amount", "bid_deadline"] | Core decision-making fields for tender announcements require precise structured extraction to improve retrieval and question-answering accuracy |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing.
Three common misconfigurations
- The symptom is irrelevant non-tender project content appearing in retrieval results. The cause is that directional data source synchronization rules are not configured, and invalid data from non-target channels is crawled.
- The symptom is out-of-vram error when multiple users initiate retrieval simultaneously. The cause is that vram allocation configuration is not adjusted based on deployed large model parameters and concurrency volume, and model quantization or batch loading is not enabled.
- The symptom is an initial root password error prompt when logging into the system. The cause is that the
INITIAL_ROOT_PASSWORDenvironment variable in docker-compose.yml is not configured correctly, or the configured value does not match the entered value.
How to confirm proper configuration
- Run an incremental synchronization task, verify that only newly added tender announcements within the specified period are imported into the knowledge base, with no historical data reloaded repeatedly.
- Upload a single complete tender announcement PDF, verify that the core fields extracted by the structured extraction module match the original document content.
- Initiate a specified number of concurrent retrieval requests, verify that the system responds without timeouts or abnormal errors.
- Modify the chunk size parameter and re-parse the same document, verify that the text segmentation results match the expected configuration.
