What the documents look like
Semi-managed sellers on Temu maintain overseas inventory and arrange shipment themselves, rather than only supplying goods to the platform. The daily document backbone for this operating category is the product declaration form, the overseas inventory table, the price declaration, and the platform fulfillment order. These materials mix Chinese product names, English declaration elements, overseas warehouse codes, and platform fulfillment order numbers in the same working set. Retrieval requests move between Chinese phrasing and English identifiers, so a single search habit rarely covers the whole document body.
Update frequency for this category is daily and per order. When parsing and chunking are not rechecked after a document change, retrieval can keep returning the earlier version of a field. That stale return affects the checks a seller performs on sellable status and on shipping timeliness.
Constraints at the document chunking step
Parsing and chunking start with the source text and its parsed result. The document identity and version that can point back to the source must be retained, so a returned chunk can be traced to the material it came from. Segmentation is checked against the structure of the specific material: a condition, an explanatory note, and the content that note constrains should not be split apart. Original data and retrieval indexes are distinct, and one group of original data can map to more than one index.
Retrieval checks use terminology, identifiers, and natural language separately, so the effect of a segmentation choice on a real question can be observed. After a material change, the actual training and index state is checked; a successful upload is not the same as an updated retrieval result. Semantic recall and relevance scores do not perform authorization or entity isolation. The same-vector-model requirement for a retrieval library does not extend to other external systems.
Hypothetical drill sample: one overseas inventory table reads "Warehouse code DE-07, product declaration name Pet Grooming Glove, sellable quantity 120, status Pending platform review. Effective date 2025-03-01." A draft sentence reads "This product has a sellable quantity of 120 in the German warehouse and has passed platform review." The question is whether the draft sentence agrees with the source text.
Configuration and implementation checks
| Configuration or check item | Hypothetical trial starting point | Reason and comparison method |
|---|---|---|
| Search mode | Semantic search and full-text search both enabled | Chinese phrasing uses semantic, English identifiers and warehouse codes use full-text; compare whether the two paths together cover the sample fields |
| Minimum relevance | Set to 0.3 for this hypothetical trial | Used to filter low-relevance results; compare against the score returned for the sample and observe whether the source chunk is kept |
| Reference limit | Set to 800 tokens for this hypothetical trial | Controls reference volume by tokens; compare whether returned content includes the complete condition clause and the status field |
| Question optimization | Enabled for this hypothetical trial | The sample contains reference and omission; compare whether the retrieval terms before and after include the full subject and object |
| Result rerank | Enabled for this hypothetical trial | Second-pass ordering when candidates are many; compare rerank score and vector score on the ordering of the sample chunk |
| Index state check | Performed after each material change | Check actual training and index state; compare the upload record with the returned retrieval content |
Three common errors
- Treating a successful upload as an updated retrieval result. Input is the upload record for the sample inventory table; compare the upload time with the returned retrieval content. If retrieval still returns the earlier quantity, the index has not been updated.
- Reading "Pending platform review" as "passed platform review." Input is the sample source phrase "status Pending platform review"; compare it with the draft sentence "has passed platform review." The two status values are mutually exclusive on the same field, and the draft sentence is not supported by the source.
- Treating a semantic search score as a permission or entity filter. Input is the sample warehouse code DE-07; compare whether the returned content includes records from other warehouses only because of similarity. If content outside DE-07 is returned, the score does not perform entity isolation.
How to verify the setup
- For the sample source text "Warehouse code DE-07, product declaration name Pet Grooming Glove, sellable quantity 120, status Pending platform review," enter the retrieval term "DE-07 sellable quantity" and compare whether the returned chunk retains the status and effective date. The condition is met when the returned content contains the complete condition clause.
- For the draft sentence "This product has a sellable quantity of 120 in the German warehouse and has passed platform review," enter the source text and the draft sentence and compare the status field values. When the draft and the source take mutually exclusive values on the same field, the draft is judged unsupported.
- For the index state after a material change, enter the changed inventory table and the pre-change retrieval term, and compare the returned quantity with the changed source text. The condition is met when the returned quantity matches the changed source text. If an empty result is returned, use the paper input [] to check the downstream design, and do not claim that a fictional rule necessarily returns empty.
