What the documents look like
For after-sales questions in Brand livestream operations, this page examines FastGPT retrieval. Retrieve spoken claims, product cards and session confirmation together in brand-stream aftercare. The examples are hypothetical.
Constraints at the retrieval step
A proposed brand-stream case says a spoken set includes a straw, marks the straw optional on a product card and refers this session to a confirmation page. The customer asks what this order includes, but that page is missing. The sources may differ by version or session. Retrieve both rather than select one automatically, comparing inclusion, optional and full questions. A newer filename does not establish applicability. Current session and order correspondence remain necessary before resolving the descriptions, and a relevant excerpt cannot supply the missing confirmation relationship.
Configuration and implementation checks
| Material check | Conditions in this test | Implementation evidence |
|---|---|---|
| Parallel sources | Speech and card | Inspect both candidates. |
| Question applicability | Current session and order | Do not generalize in optimization. |
| Confirmation identity | Current session | Do not infer from title. |
| Reference completeness | Includes, optional and sources | Retain qualifiers. |
| Current gap | Applicable confirmation absent | Do not select a side automatically. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Associated knowledge bases | Knowledge bases associated with one search node must use the same embedding model. |
Search mode | Semantic, full-text and hybrid modes are available. |
Citation limit | Citation limits are measured in tokens. |
Minimum relevance | Range 0–1; active for semantic search or reranking. |
Question optimization | Resolves references and expands questions. |
Three common errors
First, spoken wording may be recalled while the card is absent; inspect scope, versions and literal coverage instead of stopping at an answer-shaped passage. Second, optimization may replace current contents with general set information; retain session and order in both questions. Third, a returned confirmation may belong to another event; inspect event identity and actual references rather than accepting its title. These concern dual-source coverage, question applicability and confirmation attribution. Scores, timestamps or repeated keywords cannot decide which business statement applies to the current purchase.
How to verify the setup
Ask what each source states, which confirmation is missing and what can currently be supported, retaining candidates and references. Compare semantic, full-text and hybrid retrieval on identical questions with inclusion, optional status and identity kept under token limits. Added session confirmation needs this order matched before examining adoption. Without it, do not assert a binding offer or completed adjustment. This exercise configures no gift, decides no responsibility and changes no order. Failure to retrieve a source does not establish that it does not exist; scope and transfer still require inspection.
