What this category of data looks like
Data for this category comes from manufacturing enterprise MES systems, online inspection equipment, laboratory reports, process parameter documents, customer standards, and historical defect databases. Daily produced documents include control plans, patrol inspection records, SPC reports, finished product inspection reports, nonconforming product review forms, release forms, and quality monthly reports. These documents contain fields such as inspection items, defect codes, release thresholds, and batch identifiers. Organizations update this data per production batch, per shift patrol inspection, or via continuous collection of inspection and process parameters.
What constraints these characteristics impose on the knowledge base retrieval and recall link
Multi-source, heterogeneous and frequently updated data creates multiple constraints for the retrieval and recall process. Mixed document formats require retrieval to support chunking of mixed text and table content. The high-frequency update rhythm per batch and shift requires configuring an incremental synchronization mechanism to ensure the timeliness of recalled content. Professional fields such as inspection items, release thresholds, and defect codes require retrieval to match precise business semantics, to avoid generalized results. Differences in fields across documents require associating information corresponding to the business scenario and filtering irrelevant content. This ensures recalled results align with the judgment needs of process quality and finished product release.
How to configure settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Precisely match professional terms and judgment standards for process quality and finished product release, filter low-relevance generalized content |
limit | Top 8–12 entries | Cover multi-dimensional inspection records and standards, while avoiding exceeding context window limits |
searchMode | mixedRecall | Balance semantic matching and precise keyword matching, adapt to retrieval needs for mixed document formats |
usingReRank | Enabled | Reorder recalled results, prioritize returning content directly related to inspection items and release thresholds |
datasetSearchUsingExtensionQuery | Enabled | Automatically expand business-related synonyms, cover matching scenarios for more professional expressions |
collectionIds | Bind exclusive datasets for process quality and finished product release | Isolate documents from other categories, ensure recalled content aligns with this category’s business scenario |
Three common configuration mistakes
- Phenomenon: After importing control plans or SPC reports in docx or Excel formats, retrieval results contain a large number of irrelevant text paragraphs. Cause: Failure to configure applicable chunking rules for table documents causes table content to be split into scattered text blocks that cannot be accurately recalled.
- Phenomenon: The retrieval scope covers the full dataset, and recalled results include non-category content such as supplier incoming material inspection records. Cause: Failure to bind exclusive
collectionIdsmeans retrieval is not limited to the process quality and finished product release dataset. - Phenomenon: When retrieving Feishu documents with images, only text links are returned in results, and business information in images cannot be displayed directly. Cause: Failure to enable OCR parsing and associated recall configuration for image content means only text information is extracted, and inspection items or standard content embedded in images are not processed.
How to verify correct configuration
- Search for preset professional terms such as "finished product release threshold". Check whether recalled results include category-exclusive documents such as control plans and finished product inspection reports.
- Review the order of retrieval results. Confirm that reordered results prioritize displaying inspection items and judgment standards directly related to the current query.
- Verify the incremental synchronization function. Upload a new nonconforming product review form, then search the form’s number. Confirm the new content is recalled.
- Check the dataset binding status. Confirm that the retrieval scope only includes exclusive datasets for process quality and finished product release, with no cross-category content mixed in.
