What the data for this category looks like
Coal chemical industry research report data sources include public industry research reports, public documents from coal industry associations, and third-party industrial consulting reports. Routine dynamic reports are updated biweekly. Major project and policy change documents are synced in real time. Document structure includes core industry indicators, regional production capacity distribution, upstream and downstream supply and demand analysis, and policy interpretation modules. Fields include plant operation scale, raw material procurement prices, project construction progress milestones, and data related to corporate revenue proportions. Units follow legal metrology standards, such as ten thousand tons per year, yuan per ton.
Constraints imposed on HTTP interfaces and external systems by these characteristics
The multi-source nature of coal chemical industry research reports requires interfaces to support multi-data source aggregation verification to avoid data conflicts. The mixed update rhythm requires interfaces to provide both incremental pull and full pull trigger modes to adapt to different business needs. The multi-module document structure requires interfaces to support targeted recall by specified modules while retaining full-document retrieval capabilities. The multi-unit field requirement means interfaces must include built-in unit format verification to prevent parsing exceptions. External system integration needs to adapt to the timeliness requirements of data updates, with reasonable timeout and retry strategies configured.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
RETRIEVE_TOP_K | Top 10–15 results | Core indicators of coal chemical industry research reports are concentrated. Too many recall results increase context redundancy, while too few lead to insufficient coverage |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Individual coal chemical industry research reports have relatively long length, some containing large numbers of charts and data tables, leading to longer parsing time |
UPLOAD_FILE_MAX_SIZE | 500 MB | Some coal chemical industry research reports include attachments such as high-definition industry maps and production capacity distribution maps, requiring adaptation to large file uploads |
CONTEXT_WINDOW_SIZE | 8000–12000 characters | Individual coal chemical industry research reports have relatively long content, requiring adaptation to long context processing requirements |
API_REQUEST_TIMEOUT | 60 seconds | External system calls to the interface need to wait for multi-source data aggregation and parsing. An overly long timeout will affect business processes |
MCP_HTTP_ENABLE | Enabled | Supports streaming HTTP integration with external systems, adapting to real-time data synchronization requirements |
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 case-by-case analysis, and testing on local samples is recommended before finalizing settings.
Three common configuration mistakes
- Phenomenon: A 400 status code is returned when calling the retrieval interface, and the request body cannot be modified directly. Cause: Interface parameter format verification rules are not configured correctly, and non-compliant field types are passed in, triggering the parameter verification logic.
- Phenomenon: A
URIError: URI malformederror is thrown when calling the login interface. Cause: The connected coal chemical industry research report data source link contains unencoded special characters, causing the interface to fail when parsing the request URI. - Phenomenon: After deploying the external system integration container, the interface is only accessible locally, and external requests are rejected. Cause: Port binding is not set to 0.0.0.0 in the docker-compose configuration, allowing only loopback address access.
How to confirm proper configuration
- Call the interface with the exclusive retrieval keyword for coal chemical industry research reports, and check if the returned results contain corresponding industry indicators and policy content.
- View interface logs to confirm there are no parameter verification errors, and that the returned document structure matches the format of locally stored coal chemical industry research reports.
- Test both incremental pull and full pull modes to confirm that the update frequency meets business requirements.
- Verify the streaming HTTP integration function to confirm that external systems can receive returned retrieval results in real time.
