What the data for this category looks like
Auto parts research report data primarily comes from securities firm industry research institutes, domestic auto parts industry associations, and public supply chain disclosure documents from original equipment manufacturers. Update frequency fluctuates with industry events, with concentrated updates during quarterly earnings reporting periods and new product launch cycles. Individual documents typically include fields such as parts model numbers, supporting automaker lists, detailed production costs, supply chain tiering, and segmented market share percentages. Units include unit selling prices, ten-thousand-unit production capacities, gross margin percentages, and revenue share percentage points. Documents often include structured tables with nested content such as BOM lists and quarterly production capacity data.
Constraints on HTTP interfaces and external systems from these characteristics
The multi-source data sources for auto parts research reports require interfaces to support cross-data-source synchronization configuration, and adapt to file format differences across different institutions. Fluctuating update frequencies require interfaces to support dynamic adjustment of pull cycles, to avoid triggering rate limits during peak periods. The specificity of fields and units requires interfaces to include built-in standardized validation rules, to perform format checks on unit selling prices and production capacity data. Structured supply chain table content requires interfaces to support parsing nested table fields, to avoid abnormal returned data structures. The length of individual documents requires interfaces to configure sufficiently large parsing timeout thresholds, to prevent errors from being returned before long text content finishes parsing.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Auto parts research reports often contain long text tables and nested structures, with longer parsing times than general documents |
UPLOAD_FILE_MAX_SIZE | 500 MB | Single in-depth research reports may include multiple attached supply chain data tables, requiring support for large-capacity file uploads |
Recall count | Top 8 entries | Auto parts vertical segments have strong specialization; precise retrieval requires limiting redundant results, with priority given to matching model and automaker fields |
Similarity threshold | 0.72–0.85 | Semantic similarity for fields such as parts model numbers and supporting automakers must be strictly controlled, to avoid mixing in irrelevant research reports |
HTTP_SYNC_INTERVAL | 3600–7200 seconds | Research report updates have no fixed cycle; adjusting on an hourly basis balances real-time performance and interface load |
maxContext | 1200–1500 characters | The core content of research reports is mostly concentrated in supply chain and cost sections; limiting context length improves retrieval accuracy |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Directory hierarchy displays abnormally in interface returned data, with
b.mdthat should be insidedir1appearing in the upper-level folder. The cause is that the external system did not correctly carry path metadata when uploading files, or the file path parsing rules of FastGPT do not match the upload logic. - Knowledge base content can be retrieved normally on the debug page, but some queries return no results via API calls. The cause is that the API call did not carry correct session context parameters, or the correct knowledge base authorization identifier was not configured in the request header.
- Interface requests trigger timeout errors, returning status code 504. The cause is that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration was not adjusted, and parsing time for long-text research reports exceeded the default threshold.
How to Confirm Configurations Are Correct
- Initiate a single file upload request, verify that the returned file path metadata matches the specified directory structure at the time of upload.
- Call the API to retrieve research reports for a specified parts model number, check that returned result fields include preset information such as parts model numbers and supporting automakers.
- Simulate peak-period batch requests, check that interface returned status codes and error logs have no abnormalities, confirm that configured timeout and concurrency parameters take effect.
- Compare retrieval results from the debug page and API calls, confirm that the number of research report entries and similarity matching degree returned by both are consistent.
