What This Category of Data Looks Like
The policy and regulatory basis data for the fertilizers and pesticides sector is primarily sourced from official public documents issued by the Ministry of Agriculture and Rural Affairs, the Ministry of Industry and Information Technology, the Ministry of Ecology and Environment, and local agricultural and rural affairs departments. Data updates are triggered when new national or industry policies are released. A full sync of the existing policy library runs on a regular quarterly basis. Each individual document includes fields such as policy document number, issuing authority, effective date, clause category, applicable scenario, and specific text content. Most clause content is plain text, with some including official interpretation attachment links. Fields do not use complex nested units, only character count and clause serial numbers as basic identifiers.
Constraints Imposed on Citation Sources and Traceability
Officially issued policy document numbers and effective dates are the core identifiers for tracing fertilizers and pesticides policies. The traceability process must first extract the document number and issuing authority fields from the document as citation credentials. Relying solely on content fragments cannot complete valid traceability. Data is dynamically updated alongside new policies, so incremental sync logic must be configured to ensure cited policies remain active. Individual documents have a clear structure but fixed metadata fields. Complete metadata prefixes must be retained during text chunking to avoid loss of critical source information during traceability. The requirement for unique official sources means non-official derivative content must be filtered during the retrieval phase to ensure the authority of citation sources.
Configuration Guidelines
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | The length of individual fertilizer and pesticide policy clauses and associated metadata is moderate. This range fully covers core traceability information and avoids truncating critical content |
| Single search limit | Top 6 results | Policy content needs to cover documents of different levels on the same topic. 6 results balance retrieval breadth and result redundancy |
detail | Enabled | Policy document numbers, release dates and other metadata need to be returned. Enabling this ensures complete extraction of document fields for traceability |
| Reranking | Sorted by release date in descending order | Fertilizer and pesticide policies are time-sensitive. Newly released policies have higher priority, which aligns with industry reference habits |
responseData | Only return official source documents | Fertilizer and pesticide policies need to ensure authority. Non-official derivative content is filtered, and only original officially released documents are retained |
| Maximum context | 4000–5000 characters | Policy Q&A needs to associate relevant clauses from multiple documents. This range covers sufficient context association information |
Three Common Configuration Errors
- Phenomenon: Merged citation counts exceed the preset limit, causing conversation context overflow. Cause: No reasonable value is set for the single search limit, and the number of results retrieved from a single knowledge base is not restricted. This leads to excessive redundant information after merging, exceeding the context capacity.
- Phenomenon: Returned citation results only include clause content, without policy document numbers, release dates and other metadata. Cause: The
detailconfiguration is not enabled, and document metadata fields are not extracted. This makes valid source identifiers unavailable during traceability. - Phenomenon: The sorted order of policy results retrieved from the knowledge base does not meet expectations, with newly released policies not appearing at the top. Cause: No reranking rule sorted by release date in descending order is configured. Only default similarity sorting is used, which does not match the time-sensitive reference needs of fertilizer and pesticide policies.
How to Confirm Proper Configuration
- Submit a test query related to fertilizer and pesticide policies. Check the citation module in the returned results to confirm that metadata such as policy document numbers and release dates is included.
- Review the sorting of citation results to confirm that newly released policy entries appear at the top, in line with the preset reranking rules.
- View the knowledge base source tags to confirm that only documents issued by official departments such as the Ministry of Agriculture and Rural Affairs and the Ministry of Industry and Information Technology are displayed, with no third-party derivative content.
- Adjust the keywords of the test query to verify that the number of retrieved citations meets the preset single search limit requirement.
