What this category of data looks like
The data sources for agricultural commercial bank research report retrieval mainly include special analysis reports produced by the in-house research team, interpretations of agricultural-related financial policies released by regulatory authorities, and monthly tracking analysis documents of local agricultural business operators. Update rhythm is adjusted according to business needs and policy release schedules: special research reports are produced on demand, policy interpretations are updated synchronously with regulatory documents, and local tracking documents are updated monthly or quarterly. The document structure uniformly includes four modules: research background, core analysis content, business recommendations, and risk reminders. Fields include report unique identifier, release time, covered administrative region, and research subject. The length of individual documents varies widely. It is recommended to count or test based on your own samples before finalizing settings.
What constraints these characteristics impose on model access and configuration
The data sources include mixed-format policy interpretations and local tracking documents. This requires the model access link to support unified parsing and structured extraction of multi-format documents, to avoid loss of key information from unstructured content. The flexible update rhythm requires reserving parameter interfaces for dynamic index updates in the configuration, to adapt to on-demand synchronization of the latest research reports. The range of individual document lengths requires the configured model context window to cover more than 8000 characters, to avoid incomplete analysis caused by long document truncation. Fields including targeted information such as administrative region and research subject require configuring field-level filtering rules in the retrieval link, to ensure retrieval results match the user-specified region or subject scope.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8192–16384 characters | Adapts to the length of individual research reports (3000-8000 characters), reserves sufficient context to process parsed documents and user questions |
retrieveTopK | 8–12 items | Research report content has high granularity. Too many retrievals will increase context pressure, while too few will fail to cover relevant analysis dimensions |
rerankTopN | 3–5 items | User questions usually focus on core analysis points. A small number of reranked results can accurately match requirements |
searchRetrieveThreshold | 0.75–0.85 | Research reports are highly professional. A high threshold is required to filter results with low relevance to the question |
documentUpdateCycle | On-demand update / 1 hour | Adapts to the rhythm of on-demand research report production and policy synchronous updates. On-demand synchronization can avoid invalid resource usage |
modelToolEnable | Enable on demand | Enable only when external tools are needed to verify policy data, to avoid unnecessary tool call overhead |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: The test prompts "No available channel for model gpt-4o-mini under group default". Cause: No available channel for this model is bound to the default group, or the channel configuration has not been verified.
- Symptom: The toolChoice function call has no response. Cause: A model that supports toolChoice was not selected, or tool call permission was not enabled in the model configuration.
- Symptom: Core data is lost after parsing agricultural research reports with charts. Cause: No multimodal model access was configured, and only a plain text model was used to process documents containing visual content, resulting in failure to extract image information.
How to confirm the configuration is complete
- Upload a single research report document under 8000 characters, trigger a retrieval test, and verify that no context truncation prompt appears in the returned results.
- Configure field filtering rules, enter search keywords for a specified administrative region, and verify that the returned results only include research report content for the corresponding region.
- After enabling the reranking function, compare the results before and after retrieval and reranking, and confirm that results with higher relevance are ranked first.
- Trigger a document synchronization operation, verify that the background index update log shows synchronization is complete, and newly uploaded research reports can be retrieved normally.
