What data for this category looks like
Typical actors include social security handling agencies, human resources and social security bureau business departments, and street social security service windows. Daily documents include benefit application forms, payment duration certificates, retirement approval forms, work injury identification materials, and unemployment insurance benefit application materials. Data sources are social insurance handling systems, personal benefit records, labor relations and work injury identification systems, and electronic social security card platforms. The update frequency is daily. Data fields cover insured person identity information, payment duration, benefit verification standards, qualification review material numbers, and more. Units such as month, yuan, and person-times are used. The content length of single documents varies.
What constraints do these characteristics place on the vector models and indexing workflow
High-frequency data updated daily requires indexes to support incremental synchronization, avoiding performance loss caused by full reconstruction. Scenarios with mixed input of multiple document types require chunking strategies designed to adapt to the structural characteristics of different documents, preventing loss of key qualification review information due to long text truncation. The accuracy of core fields such as insured person identity and payment duration is directly linked to benefit calculation results. Vector retrieval recall accuracy must cover these core fields, while filtering invalid redundant material text. Differences in field formats across different documents require index configurations to support mixed indexing of structured fields and unstructured text, ensuring that field matching during retrieval meets business requirements.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to documents of varying lengths such as benefit application forms and work injury identification materials, avoiding truncation of key review information |
| Overlap Length | 100–200 characters | Ensures contextual coherence between chunks, covering benefit verification logic that spans chunks |
| Similarity Threshold | Calibrated based on actual testing | Adapts to retrieval matching accuracy of core fields, balancing recall rate and precision |
| Single Search Limit | Top 10 entries | Covers retrieval needs for multiple associated materials, avoiding omission of supporting documents required for benefit verification |
| defaultToken | 1000 token | Adapts to contextual length requirements during ledger summary, ensuring core content of associated documents is fully loaded |
| maxToken | 4000 token | Limits total contextual length of a single round of retrieval, avoiding exceeding model processing limits |

Three Common Configuration Mistakes
- A 503 status code error appears, prompting that text-embedding-v3 has no available channels. The cause is that the corresponding channel quota for this model is not configured, or channel allocation has an exception.
- Unable to adjust index configuration via the original interface entry; modifications must be completed on the knowledge base content page. The cause is that the interface editing entry has been adjusted, and index parameters must be calibrated via the content editing link in knowledge base management.
- The index enhancement function cannot be enabled. The cause is that the corresponding commercial version permission is not enabled for the current version; confirm the platform authorization status.
How to Confirm the Configuration is Complete
- View the vector model channel configuration page, confirm that the available channel status of text-embedding-v3 is normal.
- Submit a test document such as a standard benefit application form, check the field matching degree of the recall results after retrieval, and adjust the similarity threshold to meet business requirements.
- Enter the knowledge base management page, confirm that the enabled status of the index enhancement function meets the permission requirements of the current version.
- Perform an incremental synchronization test to verify that daily updated data can be normally loaded into the index.
