What Data Looks Like for This Category
Auto parts investment research data mainly comes from original equipment manufacturer (OEM) public financial reports, industry association supply chain reports, parts supplier disclosure documents, patent databases, and compliance certification documents. Update frequencies vary: OEM financial reports are released quarterly. Industry supply chain reports are updated monthly. Patents and compliance certification documents are added in real time as compliance changes occur. Document structures include multi-level BOM tables, cost breakdown Excel files, parameter comparison tables, and long-form research reports. Fields cover rated torque, material grades, warranty periods, and more. Units include Nm, MPa, hours, and other professional engineering units.
Constraints During Deployment and Upgrade
Multi-source, multi-format data requires deployment phase adaptation to multiple parsing rules for Excel, PDF, structured tables, and other formats. This prevents field loss. Data sources with different update frequencies require differentiated synchronization strategies. Fixed interval triggers cannot be used universally. The association between professional fields and units must be retained during parsing. Otherwise, investment research parameter matching errors will occur. The nested structure of multi-level BOM tables increases parsing time. Timeout configurations and segmentation rules must be adjusted. Upgrades must support newly added supply chain data formats.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Auto parts compliance certification documents and multi-level BOM table Excel files often exceed the size of conventional documents, so this adapts to large file upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long-form research reports and multi-level BOM tables take longer to parse; extending the timeout prevents parsing interruptions |
Segment Length | 800–1200 characters | Parts parameter tables are mostly composed of short fields; overly long segments break parameter associations, while overly short segments lose contextual information |
Recall Count | Top 8–12 entries | Investment research requires coverage of multi-dimensional parameter comparisons; too few recalls cannot support analysis, while too many increase inference load |
Similarity Threshold | 0.75–0.85 | Part models and material grades have high similarity; raising the threshold avoids recalling parameter data from unrelated product categories |
AUTO_SYNC_INTERVAL | 2:00 AM daily | Industry supply chain data and OEM financial reports are mostly updated overnight; scheduled incremental synchronization ensures knowledge base timeliness |
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.
Three Common Misconfigurations
- Issue: Accessing the deployed parsing service returns a
405 Method Not Allowederror. Cause: Reverse proxy request method allow rules are not configured correctly, or POST request permissions are not enabled during port mapping. - Issue: The team management function configuration entry cannot be found in version 4.8.17. Cause: The
ENABLE_TEAM_MANAGEMENTenvironment variable is not enabled, or the corresponding function switch is not turned on. - Issue: Knowledge base data is inconsistent across different nodes after multi-node deployment, and uploaded files cannot be accessed across nodes. Cause: Shared storage volume mounting is not configured, or vector database cluster connection parameters are not set correctly.
How to Verify Proper Configuration
- Upload an Excel file containing a multi-level BOM table, check if the parsed result retains the association between fields and their corresponding units, with no missing or misaligned entries.
- Trigger an incremental update task, check if the synchronization log displays the latest industry report data, with no timeout or parsing failure errors.
- Initiate a query for part parameters, check that the similarity of recall results meets the preset threshold, with no parameter data from unrelated product categories included.
- Access the parsing service health check endpoint, confirm that the returned status code is
200 OK, with no500 Internal Server Erroror405 Method Not Allowederrors.
