What This Category of Data Looks Like
Duty-free research report data primarily comes from professional retail trade research institutions and public industry monitoring data sources. Updates occur on an ad-hoc basis when policies for offshore duty-free and in-city duty-free shopping are adjusted, alongside regular monthly and quarterly industry analysis reports. Document structures include policy interpretation text, structured passenger flow and sales data, supply chain trend analysis, and other content. Fields cover offshore duty-free sales, average transaction value, policy effective dates, pilot region scope, and more. Units include ten thousand yuan, yuan, standard date formats, and others.
Constraints for HTTP Interfaces and External Systems
The mixed document structure of duty-free research reports requires HTTP interfaces to support mixed parsing of non-policy text and structured data. External systems must adapt to synchronization of multi-format content. Ad-hoc update nodes require external systems to configure flexible synchronization trigger mechanisms to accommodate non-fixed-cycle update points. Specific field units require interface input and output parameters to support standardized unit conversion, preventing data inconsistency between systems. Long documents and multi-dimensional data require interface parsing and request timeout settings to accommodate higher time consumption requirements.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Duty-free research reports often contain long-form policy interpretations and multi-page structured charts, leading to extended parsing durations |
UPLOAD_FILE_MAX_SIZE | 200 MB | Single duty-free industry research report PDFs frequently include multi-page data appendices and charts, resulting in larger file volumes |
maxContext | 8000–12000 characters | Policy details and structured data from duty-free research reports must be fully included in the large model context to maintain answer accuracy |
Recall count | Top 8 results | Duty-free research reports cover multiple granular dimensions, requiring sufficient relevant segments to support precise answers |
Similarity threshold | 0.75 | Distinguish core research report content from peripheral industry news to avoid irrelevant data being included in retrieval results |
API_REQUEST_TIMEOUT | 30 seconds | External system calls to the interface must accommodate the time required for multi-source data aggregation to prevent premature timeout triggers |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- API responses do not include knowledge base content. The symptom is that interfaces return only general Q&A content with no research report-related segments. The cause is that the external system did not correctly associate the knowledge base, or did not carry a valid knowledge base ID parameter during the call.
- PDF file parsing triggers a timeout error. The symptom is a
408 Request Timeoutstatus code returned. The cause is failure to adjustPARSE_FILE_TIMEOUT_SECONDSto a value suitable for long documents. Multi-page appendices in duty-free research reports extend parsing durations. - Structured data field units returned by the interface are inconsistent. The symptom is sales fields showing values in both "yuan" and "ten thousand yuan". The cause is that the external system did not configure unified unit conversion rules, and did not perform standardized processing based on the original field units of the research report data source.
How to Confirm Proper Configuration
- Call the test interface with duty-free research report-related query terms such as "Hainan offshore duty-free policy" and "in-city duty-free average transaction value". Check if returned results include research report segments from the knowledge base to confirm knowledge base association configuration is correct.
- Upload a single duty-free research report PDF with approximately 150 pages. Check if the parsing task completes within the configured timeout period to confirm the timeout setting is reasonable.
- Review structured data fields returned by the interface. Verify that units are consistent to confirm the external system's conversion rules have taken effect.
- Simulate a policy update scenario to trigger an incremental synchronization task. Check if the external system can pull the latest research report data in a timely manner to confirm the synchronization mechanism configuration is correct.
