Data Characteristics for This Category
Paint and ink due diligence data comes from annual manufacturing enterprise reports, industry association-published raw and auxiliary material test reports, environmental protection department sewage discharge permit data, and upstream and downstream supply chain transaction ledgers. Update schedules follow this pattern: raw and auxiliary material prices update every 7 days, product compliance reports update quarterly, and enterprise production data updates monthly. Single documents are mostly 10–50 page PDFs or structured tables, containing fields including product name, CAS number, VOC content, weather resistance parameters, production batch number, and compliance level. Common units are mg/m³, μm, and rating (first-class/qualified). Some documents include OCR text blocks from scanned copies.
Constraints Imposed on Deployment and Upgrade
Deployments must configure multi-format parsing adapters to handle multi-source, heterogeneous document formats. Adjust parsing timeout parameters to accommodate long texts and scanned OCR content. Optimize knowledge base incremental synchronization configurations during upgrades to handle frequently updated raw and auxiliary material data, avoiding retrieval of expired data. Configure field mapping rules for structured fields with clear units, to ensure extracted units match knowledge base metadata. Adjust segmentation parameters to handle wide variation in single document page counts, preventing critical information loss from long text truncation.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Paint and ink due diligence documents often contain long tables and scanned OCR text, with higher parsing time than general documents |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single enterprise compliance reports can reach hundreds of pages, with large combined file size |
maxContext | 8000–12000 characters | Long documents require retaining sufficient context after segmentation to associate product and compliance data |
Recall Count | Top 8–12 results | Paint and ink data has dense fields, requiring coverage of multi-dimensional parameters to support due diligence analysis |
Incremental Sync Interval | 12 hours | Raw and auxiliary material prices are updated every 7 days; frequent incremental synchronization avoids retrieving expired data |
Field Mapping Rules | Associate product data by CAS number | CAS number is the unique identifier in due diligence reports, enabling accurate matching of product parameters in the knowledge base |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: After upgrading a Docker deployment to version V4.14.7 or V4.14.8, the console prompts plugin pull failure, and the service cannot start normally. Cause: Domestic mirror acceleration address is not configured. Official image repositories experience pull timeouts in domestic network environments.
- Symptom: After upgrading to version V4.14.x, knowledge base retrieval time increases significantly with the same knowledge base and embedding model. Cause: Full-text reranking function is enabled by default, and the
rerank return countparameter is not adjusted, leading to increased additional computing overhead. - Symptom: When configuring the
qwen3-maxmodel in version V4.11.0, a 404 status code is returned with no response body. Cause: This version does not include built-in interface adaptation configuration for this model. Manual addition of model interface mapping parameters is required.
How to Verify Configurations Are Correct
- Upload a standard paint and ink compliance report, confirm parsed text fully extracts fields such as CAS number and VOC content, with no obvious truncation.
- Start an incremental synchronization task, review vector database update logs to confirm raw and auxiliary material data within the cycle has completed synchronization.
- Initiate a due diligence query, confirm no timeout alert for the
PARSE_FILE_TIMEOUT_SECONDSparameter appears in retrieval logs. - Test the model call function, confirm response bodies are normal with no 404 status code errors.
