What the documents look like
Parcel labels and handoffs sit at the point where a package leaves the warehouse. The carrier scan is the responsibility boundary. The materials handled on this page are electronic waybills, handoff lists, pickup scan records, and exception item registrations. These materials update per batch and per day. Their fields include waybill number, carrier, handoff batch, scan time, and scan status.
Product material and selection questions ask what a given waybill or handoff record states, what state it is in, and which carrier or batch applies. The vector model and index determine whether those materials can be retrieved at all. One handoff list can cover multiple waybills, and one waybill maps to one waybill number. The update frequency itself does not change how the vector model and index are configured; it affects when indexes are rebuilt.
Constraints at the vector indexes step
Knowledge bases joined in one retrieval must use the same vector model. One source data block can link to multiple indexes, and each index is checked separately against the source text. Index content should be complete and focused; retrieval coverage and index length are weighed together against the sample.
Image retrieval depends on whether an image description or image vector was generated at ingestion time. Checking only the query side is not sufficient. Semantic recall and relevance scores carry no permission or entity isolation. The same-vector-model requirement for retrieval libraries does not extend to business registration sites or other external systems.
Result ordering is a fusion of multiple recall paths and does not necessarily follow a single vector similarity order. Minimum relevance is a filter threshold, not a final ordering rule, and it applies only under semantic retrieval or when result reranking is used.
Hypothetical paper exercise sample
Handoff list source text for comparison (paper hypothetical, not a real record):
Handoff batch HZ-0417, carrier East China Express, waybill numbers YT88001 through YT88040, handoff time 2025-04-17 18:30, handoff sign-off field blank, pickup scan record shows YT88001 through YT88036 scanned, YT88037 through YT88040 with no scan record.
Draft sentence to be judged:
"All waybills in batch HZ-0417 have completed pickup scan, and carrier responsibility is confirmed."
Comparing this draft sentence with the source: the scan record covers only YT88001 through YT88036, while YT88037 through YT88040 have no scan record; the sign-off field is blank. The draft sentence claims "all completed" and "responsibility confirmed," which the source does not support.
Configuration and implementation checks
| Configuration item | Relevant setting or check on this page | Relation to the sample |
|---|---|---|
| Vector model consistency | Knowledge bases joined in one retrieval must use the same vector model; check the actual model and input type first | If handoff list and waybill materials sit under different models, they cannot be joined |
| Index and source data | One source data block can link to multiple indexes; check each index against the source text separately | Waybill number, carrier, and scan status on each waybill can serve as separate check fields |
| Index content | Build indexes from complete and focused information; weigh coverage against length using the sample | Batch number and waybill number range should enter the index in full, avoiding a partial number range |
| Image index | Image retrieval depends on whether an image description or image vector was generated at ingestion | If waybills are ingested as images, confirm the corresponding index was generated at ingestion |
| Search mode | Choose semantic, full-text, or hybrid retrieval as needed | Exact queries such as waybill number and batch number suit full-text or hybrid retrieval |
| Result review | After model or index changes, compare cited source text using the same question set | Use the HZ-0417 sample question to compare whether cited content includes YT88037 through YT88040 |
Hypothetical starting value for this exercise: if a comparison value is needed for minimum relevance, take 0.5 as a paper comparison starting point. The reason is that the sample mixes exact number queries with semantic queries, and the behavior of YT88037 through YT88040 fragments under this value needs observation. This value is only a hypothetical comparison starting point on this page, not an official default.
Three common errors
- Treating a retrieval result as an authorization conclusion. Input the draft sentence "all waybills in batch HZ-0417 have completed pickup scan." Retrieval may recall this batch material, but recall does not mean the scan was completed. Compare the scan record range in the source with the range claimed in the draft sentence, and observe whether YT88037 through YT88040 fall inside the scan record. If they do not, the draft sentence is not supported.
- Extending the same-vector-model requirement to external systems. Input two knowledge base identifiers and compare whether their vector model identifiers match. If they do not match, exclude the non-conforming one and do not run a cross-model retrieval to compare missed recalls. The observed record is: identifiers do not match, not joined.
- Treating minimum relevance as an entity or permission filter. Input a query unrelated to the handoff batch and compare whether returned content belongs to that batch. A relevance score does not exclude unrelated business or unauthorized records. If returned content involves another batch, record that observation and do not assert that permission was filtered.
How to verify the setup
- Input the hypothetical source sentence that YT88037 through YT88040 have no scan record, together with the draft sentence "all waybills have completed pickup scan." Compare the waybill number ranges each covers. Condition met: the comparison conclusion states that the range claimed by the draft sentence exceeds the source scan record range, and the sentence is not supported.
- Input the vector model identifiers of two knowledge bases. Compare whether the identifiers match. Condition met: when identifiers match, record that they can be joined; when identifiers do not match, record that the non-conforming one is excluded and no cross-model retrieval comparison is performed.
- Input an exact query containing only waybill number YT88001. Compare whether the returned cited content includes the source fragment for that waybill number. Condition met: the cited content can be checked against the corresponding source fragment. If the return is an empty array, carry the empty result into the downstream design check and do not claim that an invented rule necessarily returns empty.
