What the Data for This Category Looks Like
Source data for grain reserve ledgers comes from warehouse management system inbound and outbound records, inventory check reports, grain quality inspection reports, rotation execution orders, and similar materials. Data updates trigger with business actions. Corresponding records generate after each inbound or outbound operation. Full inventory summary data updates after quarterly inventory checks. Each document has structured fields and unstructured notes. Structured fields include grain category, storage warehouse number, batch number, inbound date, inventory weight, and quality inspection grade. Unstructured sections have quality inspection abnormality explanations and rotation plan notes. Field units are mostly tons, batch numbers, and standard date formats.
Constraints for Knowledge Base Retrieval and Recall
Grain reserve data has many structured fields with precise business identifiers, such as batch numbers and storage warehouse numbers. The knowledge base retrieval and recall system must support both semantic matching and precise field matching. This stops irrelevant grain category or warehouse data from appearing in results. Data updates trigger with business actions. New data generates after each inbound or outbound operation or quarterly inventory check. Configure an incremental synchronization mechanism to ensure the latest information enters the knowledge base promptly. This prevents outdated inventory records from being recalled. Individual document lengths vary widely. Short inbound and outbound records mix with long inventory check reports. The system must adapt to recall fragments of different lengths. This ensures complete associated data is available during ledger summary. It also reduces redundant information that interferes with report generation.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
similarity | 0.65–0.75 | Grain reserve data includes precise business fields. A threshold that is too low adds irrelevant warehouse record data. A threshold that is too high may miss relevant batch records. This range is calibrated based on actual testing. |
limit | Top 8–12 entries | Ledger summary needs to cover major associated inbound/outbound and inventory check records. Too many entries exceed the context window. Too few entries miss critical data. |
searchMode | Hybrid retrieval | FastGPT v4.17.0 and later versions support hybrid retrieval. Data includes both structured precise fields and unstructured quality inspection notes. Hybrid retrieval balances semantic association and precise matching. |
usingReRank | Enabled | Long inventory check reports and short inbound/outbound records mix together. Reranking filters low-correlation results and improves recall accuracy. |
datasetSearchUsingExtensionQuery | Enabled | Ledger summary queries often include extended business requirements. Optimized queries recall more relevant historical records. |
collectionIds | Bind to the exclusive grain reserve knowledge base collection ID | Isolate data from other categories. This prevents cross-category recall from interfering with ledger summary logic. |
Three Common Mistakes
- The symptom is an "access denied to dataset" error during retrieval. The cause is failing to bind the current workflow to the exclusive grain reserve knowledge base collection, or setting the collection permission to private without opening access.
- The symptom is that retrieved fragments cannot link to the original file's online preview link. The cause is failing to enable the knowledge base's original file association configuration, or failing to retain the original file's complete path information during chunking.
- The symptom is that the number of retrieval results does not match the configured parameters. The cause is failing to correctly set the
limitparameter, or failing to retain enough pre-recall entries after enabling reranking, leading to result filtering.
How to Verify Proper Configuration
- Run a single business query. Check that the similarity of returned results falls within the preset range.
- Check the knowledge base synchronization records. Confirm that the latest business data has completed incremental synchronization.
- Inspect the bound knowledge base collection. Confirm that it only contains document data related to grain reserves.
- Trigger a ledger summary task. Check that the number of recalled fragments matches the configured parameters.
