What this category of data looks like
This category of data mainly comes from the centralized treasury payment system, integrated budget management system, electronic invoice platform, and contract management system, with a daily update frequency. Staff process documents including payment applications, fund use plans, invoices, contracts, acceptance documents, reimbursement approval forms, and payment vouchers every day. Each document type includes fixed fields such as budget indicators, economic classification, payment amount, contract terms, and acceptance results. The system generates data around the compliance and execution details of a single fund payment, with no additional statistical aggregation fields.
Constraints imposed on knowledge base retrieval and recall by these characteristics
Data sources are scattered across multiple business systems. Retrieval must support cross-system recall of related documents and multi-dataset linkage. Documents update once per day, so knowledge base synchronization frequency must match business update rhythms to avoid retrieving expired data. Fields for single fund-related documents are fixed and closely linked. Retrieval must accurately match core fields such as budget indicators and economic classification to prevent irrelevant results from disrupting audits. Single data volume is small, but associated chains are long. Administrators must control the relevance and number of retrieved results to help auditors quickly verify the complete payment chain.
Configuration settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.72–0.85 | Core audit fields such as budget indicators and economic classification require precise matching to avoid low-similarity irrelevant documents being included |
limit | Top 6–10 | The associated document chain for a single payment is long, so it needs to cover all links such as invoices, contracts, and acceptance documents, while controlling the number of single-round retrieval results to avoid overload |
searchMode | Hybrid vector retrieval + keyword retrieval | Documents include structured fields and unstructured terms, and hybrid retrieval can match both numerical indicators and textual contract content |
usingReRank | Enabled | Retrieved results need to be reordered by relevance to the current audit request to ensure core compliance basis is displayed first |
datasetSearchUsingExtensionQuery | Enabled | Automatically expand associated query terms such as economic classification and budget subjects related to audits to cover potentially related documents |
collectionIds | Bind the IDs of the three datasets: treasury payment, electronic invoice, and contract management | Retrieve business system documents exclusive to this category to avoid interference from irrelevant datasets |
Three common misconfigurations
- Issue: Retrieval results include historical documents not updated on the current day. Cause: No knowledge base synchronization task configured to match the business update frequency, resulting in expired data being retrieved.
- Issue: The external knowledge base interface returns an authentication failure. Cause: Interface authentication parameters are not handled correctly, and the automatically supplemented token does not meet the target system’s requirements.
- Issue: Retrieval results have insufficient relevance, and cannot match the corresponding relationship between budget indicators and economic classification. Cause:
datasetSearchUsingExtensionQueryis not enabled, and associated query terms are not automatically expanded.
How to verify correct configuration
- Manually trigger retrieval, and check whether the update time of retrieved documents matches the daily update rhythm of the business system.
- Access the retrieval configuration panel, and confirm that the three exclusive datasets of centralized treasury payment, electronic invoice, and contract management are bound.
- Submit a test request containing budget indicators and economic classification, and check whether retrieval results cover all chain documents such as invoices, contracts, and acceptance documents.
- Call the external knowledge base interface, and confirm that returned authentication parameters meet the target system’s format requirements.
