What Data for This Category Looks Like
Data sources for oilfield engineering service documents include construction records for each process, technical design plans, completion acceptance reports, industry quota standards, safety operation procedures, and more. Data update cadence adjusts in real time alongside individual project progress. Existing documents are updated synchronously when industry specifications are revised. Document structures typically include fields such as project number, operation block, process name, technical parameters, operation duration, and responsible team. Units involve engineering-specific units like cubic meters, megapascals, hours, and tons.
Constraints Imposed by These Characteristics on Citation Source and Traceability
Document lengths vary widely, from several pages of safety procedures to tens of thousands of words of full project construction records. This requires balancing context length and retrieval accuracy during searches, to avoid losing critical engineering parameters due to truncation. Fields include professional technical parameters and operation dimension information. Traceability requires precise matching of document segments corresponding to parameters; vague title-only searches cannot meet compliance traceability requirements. Data is updated in real time alongside project progress. This requires ensuring cited sources are the latest version of documents, to avoid referencing expired construction standards or parameters. Most source documents are associated with specific operation areas and process nodes. Traceability information must include these dimensions to meet engineering compliance review requirements.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 characters | The length of single-segment professional content in oilfield engineering documents falls within this range, preventing truncation of critical technical parameters |
| Similarity threshold | 0.75–0.85 | High precision is required for professional term matching. A threshold that is too low will introduce irrelevant engineering documents, while a threshold that is too high will result in insufficient recall |
| Single search limit | Top 6 results | Associated reference documents for a single engineering document typically do not exceed 5. Retaining redundancy helps avoid missing relevant content |
| Reranking | Enabled | Professional documents contain many similar terms, and reranking can improve the sorting priority of highly relevant segments |
detail | Enabled | Field information of cited documents (such as operation block, project number) must be returned to meet traceability compliance requirements |
responseData | Include document path, update time | Engineering document traceability requires clear source version and storage location to ensure traceability |
Three Common Mistakes
- Phenomenon: After enabling reranking, citation segments are empty, and no matching content appears in search results. Cause: The reranking logic does not match the similarity threshold, causing eligible segments to be filtered out.
- Phenomenon: Timeout errors occur during calls. Cause:
quoteMaxTokenwas not adjusted to adapt to long documents, leading to retrieval and context splicing time exceeding the default threshold. - Phenomenon: Cited sources do not include professional fields such as operation block or project number. Cause: The
detailconfiguration was not enabled, and only document titles were returned, failing to meet the precision requirements for engineering traceability.
How to Verify Proper Configuration
Reference only; verify against the target FastGPT release and deployment documentation.
- Generate a test for drafting a single engineering document, check whether the output includes the field information of the citation source, and confirm that the configuration is active.
- Check the length of citation segments, confirm that no critical technical parameters have been truncated, matching the set context length.
- Adjust reranking and similarity threshold, verify whether recall results under different thresholds conform to the matching logic of engineering documents.
- Check the update time and document path of the cited source, confirm that necessary traceability information is returned.
