What data for this category looks like
This category of data typically comes from the national government service platform's "One Task" special zone, local integrated government service platforms, electronic certificate repositories, and approval systems of various departments. The update frequency is daily. Commonly processed documents include joint handling item lists, one-time notice sheets, joint handling application forms, material circulation sheets, parallel approval opinions, completion receipts, and similar documents. Each document usually contains fields such as item code, lead department, list of parallel departments, material details, approval circulation nodes, and completion status. There is no unified fixed format, and differences exist based on the type of joint handling item.
Constraints on vector models and indexes from these characteristics
Decentralized data sources and inconsistent formats demand vector models support multi-source heterogeneous text representation. This prevents loss of key information due to format differences. Daily update frequency requires the index component to support incremental synchronization. Full reconstruction is not needed to control resource usage. The cross-department association attribute of joint handling items requires indexes to retain association relationships between nodes and materials across different documents. This prevents splitting that breaks approval circulation logic. Document content spans from item lists to completion receipts. Chunking rules must match different text lengths to ensure vector representations accurately cover cross-department material reuse and approval logic.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the average length of joint handling item documents, covering material details and approval node content |
| Overlap Length | 100–150 characters | Avoids breaking cross-node association logic after chunking, ensuring continuity of vector matching |
defaultToken | Calibrated based on actual measurements | Adapts to text token consumption in joint handling scenarios, matching the content density of daily documents |
maxToken | 4096 token | Matches the input limit of mainstream vector models, ensuring complete representation of long joint handling item documents |
| Similarity Threshold | 0.75–0.85 | Distinguishes the degree of association between joint handling items, avoiding mismatched unrelated cross-department materials |
| Single Retrieval Limit | Top 10 entries | Controls retrieval resource usage, covering core associated documents for joint handling items |
Three common configuration errors
- When using chunk mode to call the pushdata API for upload, the interface remains in the "Indexing" status for a long time. The cause is that the incremental indexing trigger rule is not configured, or chunking parameters do not match document length, leading to chunking timeout.
- Calls return an error message stating "This token is not authorized to use the model". The cause is that a valid access key for the corresponding model is not configured on the platform, or an unauthorized model identifier is used.
- Direct calls to the specified embedding model fail, and use of one API for relay is required. The cause is that the access address and key of the native embedding model are not configured in the platform settings, and only the one API proxy channel is enabled.
How to confirm configurations are correct
- Upload a single joint handling item list document, wait for indexing to complete, then search for keywords within the document, and verify that the relevance of returned results meets business expectations.
- Check the platform's indexing task logs, confirm that incremental synchronization tasks trigger at the daily update frequency, with no abnormal records of full reconstruction.
- Verify the embedding model configuration information, confirm that the used model identifier and access key match business requirements, and do not require relying on relay channels.
- Upload a material circulation sheet containing cross-department associated content, verify that the chunked vector representation does not break node associations, and that retrieval results can cover associated documents.
