What the documents look like
Group-buy leader operations centre on community nodes and commission settlement. The working materials are leader agreements, commission tables, pickup lists and community announcements. They are updated daily and per group, and they sit across the operations back office, leader chat groups, order details and after-sales records. A leader agreement sets the cooperating parties and the settlement basis. A commission table lists amounts payable by group and by period. A pickup list records goods and pickup status. A community announcement carries short-lived notices. The structures differ sharply: agreements are long clause-based text, commission tables are rows and columns of values, pickup lists are forms, and announcements are short sentences. If chunking separates an agreement condition from the commission basis it constrains, the comparison loses the shared field it depends on.
Constraints at the document chunking step
Parsing must first check the source structure against the parsed result and retain a document identity and version that can point back to the source. Segmentation completeness requires checking paragraphs against the specific material structure; a condition, its explanation and the content it constrains must not be split apart. Data and indexes must be distinguished: one set of original data can correspond to multiple indexes. Sample retrieval should use a term, an identifier and a natural-language question separately, to check how segmentation affects real questions. After a material changes, the actual training and index state must be checked; a successful upload does not mean retrieval has updated. Retrieval and relevance do not carry permission or entity isolation, and retrieval is not authorization.
Hypothetical paper exercise sample: the source text reads "Party A: a community group-buy platform; Party B: group leader Zhang; cooperation period: 1 January 2025 to 31 December 2025; commission is settled at five percent of the amount confirmed in the pickup list for the month." A separate commission table states "Zhang, March 2025, confirmed pickup amount 10,000 yuan, commission payable 500 yuan." The draft sentence to be judged is "Zhang's March 2025 commission has been settled." That sentence concerns settlement status. The source gives only the amount payable and states no payment fact and no payment date, so the sentence is unsupported.
Configuration and implementation checks
| Configuration item | Hypothetical starting point for this exercise | Reason and comparison method |
|---|---|---|
| Search mode | Hybrid retrieval | The agreement carries clause semantics while the commission table carries identifiers and amounts, so semantic and full-text recall are combined through RRF |
| Reference limit | 3000 tokens as the hypothetical starting point | Materials contain long agreement sentences and table rows; compare with 1500 tokens and observe whether a conditional sentence is truncated |
| Minimum relevance | 0.35 as the hypothetical starting point | Compare with 0.2 and observe whether low-relevance fragments enter the references |
| Question optimization | Enabled | Compare with disabled and observe whether the subject is completed across follow-up turns |
| Result reranking | ReRank enabled | Compare with RRF alone and observe changes in candidate ordering |
| Segmentation check | Check paragraph by paragraph against material type | Compare with whole-document ingestion and observe whether conditions and constraints stay in one chunk |
Three common errors
- Treating a successful upload as an updated index. Input: a changed commission table. Compare the upload state with the training state, and observe whether retrieval still returns the old amount. When the training state has not been checked, whether the update took effect remains unknown.
- Treating an amount payable as settled. Input: the draft sentence and the commission table source. Compare the field "commission payable" with "settlement status" and observe whether the source states a payment fact. When the source states none, the sentence is unsupported.
- Using a similarity filter in place of a permission decision. Input: a retrieval request. Compare the returned content with the access scope and observe whether material outside that scope appears. A similarity setting does not exclude unauthorized records, and retrieval does not constitute authorization.
How to verify the setup
- Input the hypothetical sample source and the draft sentence. Compare "commission payable 500 yuan" with "has been settled" and observe whether the system flags that the source states no payment fact. The expectation is met when that flag appears.
- Input the two versions of the commission table, before and after the change. Compare the training state field and observe whether retrieval returns the post-change amount. Returning the pre-change amount is recorded as the index not having updated.
- Input the term "commission", the identifier "March 2025" and the natural-language question "how is Zhang's March commission calculated". Compare the three recall paths and observe whether the conditional sentence returns in the same chunk. The expectation is met when all three paths can point back to the source.
