What the documents look like
Douyin storefront shelf operations center on product cards and shop experience scores. The daily materials are product qualification pages, experience score breakdowns, shipping violation appeals, and shop announcements. These materials update daily or per order, and the bulk of working time goes to maintaining experience scores, handling out-of-stock situations, and supplementing product qualifications. Operating reviews and exception retrospectives require locating the subject, object, status, and validity scope inside one material, then comparing them item by item against a draft sentence or a handover request.
The retrieval step only recalls existing library content as references. The reference output is an array whose length can be 0, and the output path still completes when no content is found. This page addresses one task only: Douyin storefront shelf operations, operating reviews and exception retrospectives, knowledge base retrieval and recall. It does not treat retrieval or any form as authorization to execute.
Constraints at the retrieval step
The knowledge base search node can associate one or more knowledge bases that use the same vector model. Bases using different vector models cannot be associated together. During implementation, check the vector model identifier first, exclude non-matching bases, and record the actual observation. Search modes are semantic search, full-text search, and hybrid search. Hybrid search merges multiple result paths through RRF; RRF is a fusion process and not a standalone switch. The minimum relevance score takes effect only under semantic search or when result reranking is used. It is a filtering threshold and does not perform permission or entity isolation. The reference limit is measured in tokens and controls how much content each search may cite. Question optimization performs coreference resolution and question expansion and adds one model call before retrieval.
Hypothetical paper exercise sample: a Douyin shop has a product qualification page. The source text reads: "The insulated cup sold through this shop's product card has a qualification page stating the subject is a certain trading firm, the qualification is valid until August 31, 2026, and the current status is submitted and pending review." A draft sentence reads: "The qualification for this insulated cup has been approved and the product can be listed and sold normally." The request to be judged reads: "Please confirm whether this product's qualification is effective and arrange listing." The source text states only submitted and pending review; it does not state approval or effectiveness. Pending review does not show a lack of operating permission, and it does not equal approval. Retrieval can recall this source text; authorization and listing execution require a separate downstream implementation.
Configuration and implementation checks
| Configuration item | Content for this page | How to check |
|---|---|---|
| Associated knowledge bases | The bases holding product qualification pages, experience score breakdowns, shipping violation appeals, and shop announcements | Check that the vector model identifiers match across bases, exclude non-matching ones, and record the observation |
| Search mode | Compare semantic, full-text, and hybrid search against the test question | Observe the three recall paths for the same question; do not assume one mode suits all materials |
| Reference limit | Unit is tokens; controls the amount of content cited per search | Test with actual materials of different lengths to see whether content stays complete, then adjust the limit |
| Minimum relevance score | Takes effect only under semantic search or when result reranking is used | Label relevant and irrelevant samples first, then adjust the threshold; do not treat it as a permission filter |
| Question optimization | Used for coreference resolution and question expansion | Compare the original question with the optimized question and check whether the subject was altered incorrectly |
| Result reranking | Requires a ReRank model and must be enabled per settings | Rerank candidate text a second time and filter by the rerank score |
Hypothetical trial starting point for this exercise: set the reference limit to 800 tokens. The reason is that the sample source text is about 120 characters and needs to hold several candidates from the same base. Compare against 400 and 1600 to observe content completeness, checking whether the subject or status field is truncated. This value is only a hypothetical starting point for this exercise and is not an official default.
Three common errors
- Treating pending review as approved. Input is the qualification page source text above and the draft sentence; compare "submitted and pending review" with "approved." The draft sentence is judged unsupported. Judging it approved directly treats an unstated status as a confirmed fact.
- Treating retrieval recall as authorized execution. Input is the request "arrange listing"; compare the retrieval output with the authorization boundary. Retrieval returns only reference content and produces no approval, listing, or synchronization action. Executing listing directly from reference content treats retrieval as authorization.
- Treating the minimum relevance score as a permission filter. Input is one unrelated shop record and one record for this shop; compare their recall. The minimum relevance score filters by score only and does not distinguish subject ownership. Assuming a higher threshold excludes other shops' records confuses filtering with isolation.
How to verify the setup
- Input the qualification page source text above and the draft sentence. Compare the source status field "submitted and pending review" with the draft sentence "approved." The condition is met when the draft sentence is marked unsupported and the source text is recalled in full. If the draft sentence is marked confirmed, the condition is not met.
- Input the request "arrange listing." Compare the retrieval output array with authorization records. The condition is met when the output contains only reference content and no approval or listing status change occurs. If an automatic listing action appears, the condition is not met.
- Input an explicitly papered empty result [] and a downstream handling design. Compare whether the downstream continues on the empty reference. The condition is met when the empty-result path is not interrupted. Do not claim that a fabricated rule search necessarily returns []; rely on actual observation.
All of the above is paper checking; no deployment or testing occurred. The missing review conclusion, effective date, and authorization records remain unknown and are recorded as evidence gaps.
