What the Data for This Category Looks Like
Work brief compilation data comes from special progress updates, monthly or weekly work briefs submitted daily by various business departments. Updates are synchronized after fixed cycles or upon completion of special task nodes. A single compilation includes 10 to 50 individual briefs. All documents follow a unified structure with five core fields: title, submitting entity, submission date, work progress, pending coordination matters, and next-step plan. Some compilations also include transcribed text from scanned attachment files.
Constraints Imposed on Embedding Models and Indexing
The fixed structure and multi-brief collection characteristics of work brief compilations require the indexing process to retain metadata for each original brief. This metadata includes submitting entity and submission date, enabling traceability of search results. Individual briefs vary widely in length. Some contain long paragraphs of work progress descriptions. Chunking must adapt to text length to avoid truncating core content. The fixed update cycle and task-node-triggered update rhythm support configuring incremental indexing tasks. This reduces resource usage from full indexing runs. Compilations with transcribed attachments require processing both structured fields and unstructured text. This ensures embedding extraction covers all valid information.
Configuration Setup
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
maxToken | 8192 token | Matches the maximum context input limit of the Qwen3-Embedding-8B model, preventing truncation of work brief content |
| Chunk Length | 800–1200 characters | Aligns with the core content length of individual work briefs, ensuring complete work progress and plan information is retained after chunking |
| Overlap Length | 100–150 characters | Prevents chunk boundaries from cutting off key pending coordination matters or next-step plan content, maintaining coherence of search context |
| Similarity Threshold | 0.65–0.75 | Distinguishes relevant brief content from noisy information, adapting to multi-document compilation search scenarios |
| Single Search Limit | Top 10 results | Focuses on core relevant work briefs, reducing filtering costs from redundant results |
defaultToken | 2048 token | Balances context capacity during retrieval and interface response speed, supporting daily retrieval needs |
Three Common Misconfigurations
- File status remains "Indexing" with no progress updates. This occurs when the embedding model call path is misconfigured, or the port for a locally deployed embedding model is not open, preventing indexing requests from completing.
- Existing configuration is overwritten after adding an identically named embedding model. This happens when a unique model identifier is not set for different deployment instances. The system overwrites stored configurations by model name by default.
- Unstructured attachment content unrelated to the target brief appears in search results. This occurs when no filtering rules for structured metadata are configured, and fields such as submitting entity and submission date are not used as retrieval constraints.
How to Verify Correct Configuration
- Access the FastGPT model management interface, confirm that the embedding model name, deployment address, and configuration parameters match the intended setup.
- Upload a single test work brief, check if indexing progress completes within a reasonable time frame with no abnormal errors.
- Run a retrieval test, verify that the number and relevance of returned results align with the preset similarity threshold and search limit rules.
- Configure an incremental indexing task, confirm that regularly updated compilation content is automatically synchronized to the vector database.
