What the documents look like
Fresh-food weighing and sorting happens inside the warehouse fulfillment stage, and the core data is weight and specification. The documents that matter for after-sales answers are the sorting task sheet, the weighing label, the short-weight compensation form, and the quality inspection record. These materials come from the WMS, the electronic scale, the order system, and inspection photos. Their update frequency is per order or per day.
Short shipment payouts, gross-margin loss, and poor customer reviews are the direct consequences of getting this wrong. When an answer cites a source, it has to be possible to locate the specific document and weighing record behind it. A fluent answer is not evidence that the cited record exists or that its content matches. The sorting task sheet and the weighing label carry the order identifier, the item, the target specification, and the recorded net weight. The quality inspection record carries the appearance and defect findings for the batch. The short-weight compensation form carries the claimed shortage and its handling stage. Each of these documents has its own scope and its own date. A citation that points to one document cannot be used to support a statement that only appears in another.
Constraints at the citation tracing step
The knowledge base search node outputs a reference array, and the length of that array can be zero. When no content is found, the output path still runs through. An empty array does not mean the workflow has errored and stopped. The node requires that the knowledge bases selected for vector search share the same vector model. Knowledge bases on different vector models cannot be associated together for this search. The retrieval result then goes to the answering step, where the answer text is checked line by line against the cited source text.
Hypothetical drill sample: a front warehouse sorting task sheet dated 12 March 2025 states "Order A, item is loose apples, target specification 500g plus or minus 20g, sorter has weighed and applied the label, weighing label records net weight 486g." A quality inspection record for the same date states "this batch of apples passed appearance inspection, no damage." A draft sentence awaiting judgment reads: "Order A has completed sorting, net weight 486g, quality inspection passed, ready to ship." Checking this sentence requires confirming that the net weight in the draft matches the weighing label, and that the inspection conclusion matches the quality inspection record. The shipping status is not stated in the supplied materials and remains unsupported.
Configuration and implementation checks
| Configuration item | Hypothetical trial starting point | Reason for the choice and comparison object |
|---|---|---|
| Associated knowledge bases | Select only the sorting document base on the same vector model | Compare against a knowledge base identifier on another vector model and exclude the non-matching one |
| Search mode | Hybrid search | Compare against semantic search used alone in terms of recall range |
| Reference limit | Hypothetical starting point 2000 tokens | Compare against the length of a document paragraph so a single task sheet is not truncated |
| Minimum relevance | Hypothetical starting point 0.3 | Compare against the number of returned items with no threshold set, to observe whether irrelevant fragments decrease |
| Question optimization | Enabled | Compare against the retrieval result for a follow-up question when it is disabled |
| Result rerank | Enabled | Compare against the ordering produced by RRF fusion alone |
The numeric values above are hypothetical trial starting points for this drill and are not official defaults. The settings in the table come from search parameters described in the official documentation. The business verification actions require human execution. Retrieval is not authorization, and a relevance score does not filter out unrelated businesses or unauthorized records.
Three common errors
- Treating the retrieval output as an authorization conclusion. The search node returns a reference array, and retrieval by itself does not constitute shipping authorization or compensation approval. In the hypothetical sample, the draft sentence says "ready to ship," while the materials do not state shipping approval. That conclusion is unsupported.
- Associating knowledge bases on different vector models. The official documentation requires selecting knowledge bases that share the same vector model. An association across models does not meet the condition. Check the identifiers first and exclude the non-matching one.
- Treating an empty reference array as a workflow failure. The reference content length can be zero, and the empty array still runs through the output path. The downstream design that receives this output needs a separate check.
How to verify the setup
- Input the sorting task sheet and weighing label text from the hypothetical sample, then compare the net weight of 486g in the draft sentence against the label record. If they match, the net weight portion is supported. If the materials do not state shipping status, that portion remains unsupported.
- Input the quality inspection record text from the hypothetical sample, then compare "quality inspection passed" in the draft sentence against the conclusion in the inspection record. If the record states only that appearance passed and other inspection items are not stated, the conclusion cannot be extended to a full quality pass.
- Input a reference array explicitly marked as empty, then check whether the downstream answering step handles it as an empty result. This check uses a paper input and does not claim that a fictional rule search will necessarily return an empty array.
