What the documents look like
Dealer ordering events serve offline dealer reservations and do not directly manage platform storefronts, which separates this category from platform multi-store matrix management. The materials handled on this page fall into four groups: the ordering handbook, the ordering contract, the sample list, and credit approval records. The ordering handbook carries new-product policy and ordering rules, the sample list carries item numbers and pack specifications, and credit approval records carry the approving entity, the credit amount, and the validity period. Together these three support inventory procurement decisions. Material updates follow a quarterly and annual rhythm, and the parsing and chunking arrangement is reviewed on that rhythm without introducing batch synchronization or real-time triggers.
The ordering handbook often places policy clauses and the dealer scope they apply to in the same paragraph. Chunking must keep a condition together with the content it constrains, so the applicable scope is not split into a neighboring chunk. Item numbers in the sample list are exact-match objects, and the full-text retrieval path suits them better than semantic matching. Credit approval records contain three field groups—entity, amount, and validity period—and after chunking each block must still point back to the original document version.
Hypothetical drill sample. The source text provided for checking reads: "East China Region 2025 Spring Ordering Event Ordering Handbook, Section 3: This season's new A-class item numbers accept reservations; the per-dealer reservation ceiling is 800 units; the applicable parties are dealers that have signed an annual dealership agreement. Sample List SC-2025-03 lists A-class item numbers A1201 and A1202, with specifications of 12 units per carton and 24 units per carton respectively. Credit Approval Form CR-2025-017 states: the entity is the East China regional dealer, the credit amount is RMB 600,000, the validity period runs to 30 June 2025, and the status is pending review."
The draft sentence to be judged: "This dealer has completed credit approval and may execute a reservation of 800 units of A-class item numbers." Basis for judgment: the credit approval form status is pending review and does not state that approval was granted; 800 units is the per-dealer ceiling stated in the handbook, and the draft sentence treats it as an executable quantity. The draft sentence is unsupported on both the credit status and the execution action.
Constraints at the document chunking step
The primary task on this page is document parsing and chunking for inventory procurement and supplier materials. Retrieval quality here depends on how each source document is segmented, because the four material types have different internal structures. Handbook policy paragraphs mix conditions with constrained content; sample lists are short exact-value records; credit approval forms are field-structured records with a status field. A chunking plan that treats all four the same way will place policy scope and item specifications into shared blocks and break the ability to trace a block back to its source.
Retrieval is not authorization. A similarity score is not a category, entity, or permission filter, and no similarity setting excludes unrelated businesses or unauthorized records. Finding a credit approval form through search does not mean the approval was granted, and finding a handbook ceiling does not mean a dealer may order that quantity. Forms collect values; business verification, approval, database writes, and external synchronization require their stated downstream implementation. The status field in the hypothetical sample remains pending review, and that gap stays open.
The documented retrieval chain combines several paths. Question optimization performs referent resolution and question expansion before retrieval. Semantic retrieval, full-text retrieval, or hybrid retrieval recalls candidate content. When the input contains images, image description retrieval or image vector retrieval is added according to model capability. RRF merges results from multiple channels. ReRank performs a second ordering, and the final output passes similarity filtering and citation ceiling trimming. These optional paths do not all run on every request: image retrieval requires an image input and model capability, and reranking requires a ReRank model enabled in the settings.
Configuration and implementation checks
| Configuration item | Value or check on this page | Basis and notes |
|---|---|---|
| Search mode | Hybrid retrieval | Item numbers need exact hits and policy clauses need semantic recall |
| Minimum relevance | Hypothetical trial start 0.4 | Compared with 0.3 and 0.5 to observe recall and noise; not an official default |
| Citation ceiling | Measured in tokens, hypothetical start 3000 | Compared with 2000 and 4000 to observe whether policy clauses are truncated |
| Question optimization | Enabled for multi-turn follow-up scenarios | Can be disabled for single clear questions, decided by observed effect |
| Result reranking | Enabled when candidates are numerous | Requires a ReRank model enabled in settings |
| Post-update review | Check training and index state after material changes | A successful upload does not mean retrieval has updated |
The citation ceiling uses the documented token unit. A relevance score is not a category, entity, or permission filter. The minimum relevance value applies only under semantic retrieval or when result reranking is used, and it is a filtering threshold rather than a final ordering rule. The three-column table above lists documented settings and implementation checks tied to this page's documents; it does not copy database internals as mandatory configuration.
Three common errors
- Treating the credit approval form status "pending review" as approved and judging the reservation executable on that basis. Check: input the credit approval form source text, compare the status field value with the draft sentence wording, and when the status is pending review the draft sentence does not hold.
- Treating the per-dealer ceiling of 800 units stated in the ordering handbook as this dealer's actual orderable quantity. Check: input Section 3 of the handbook and the credit approval form, compare the ceiling field with the actual credit status, and observe that the two are different facts.
- Merging the chunk for sample list item number A1201 with the handbook policy clause into a single citation block, so specification and applicable scope are mismatched. Check: input the sample list and the handbook source text, compare the source positions each chunk points back to, and confirm that specification and policy each remain independent.
How to verify the setup
- Input the handbook source text and the draft sentence from the hypothetical sample, compare the draft sentence's statement that credit approval is completed with the status field of the credit approval form, judge it unsupported when the status is pending review, and record that observation.
- Input item number A1201 and the natural-language question "What is the reservation ceiling for A-class item numbers," compare whether the returned blocks hit the sample list and the handbook policy clause separately, and observe whether the two blocks keep their own source boundaries.
- Input the paper empty result [] and check how the downstream design presents a no-recall case, recording the actual observation without presuming an empty result will necessarily appear. After a material change, check the training and index state and record the actual observation, without treating a successful upload as retrieval having updated.
The verification steps above test the named primary task of document chunking for procurement materials. They inspect specific proposed wording against the supplied source text and its limitations. They do not drift into identity certification, report analysis, or another task. Missing evidence remains missing: the pending credit approval is not an approval, the handbook ceiling is not an executed reservation, and an unsigned or unapproved record is not a completed business action.
