What the documents look like
For after-sales questions in After-sales repairs and reships, this page examines FastGPT retrieval. Retrieve latch, cover plate and parcel identities without merging same-model replacement parts. The examples are hypothetical.
Constraints at the retrieval step
A proposed replacement case reports a broken latch, lists latch and cover plate separately and dispatches a cover plate. The customer asks about latch dispatch. A shared device model cannot make the other part include the latch. Retrieve component and shipment objects with literal latch, plate and full questions. The application supplies no inspected fault, while plate shipment does not establish restored use. Current latch evidence remains missing. The exercise must not merge same-model parts or extend the available dispatch passage to an unlisted component in the customer request.
Configuration and implementation checks
| Material check | Conditions in this test | Implementation evidence |
|---|---|---|
| Requested part | Latch | Do not expand to whole set. |
| Dispatched object | Cover plate | Do not substitute for latch. |
| Optimized composition | Set relationship absent | Do not add inclusion. |
| Logistics attribution | Current request parcel | Inspect identity and model. |
| Outcome stage | Sending and receipt | Seek separate evidence. |
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, plate dispatch may answer latch progress; compare candidate part with original identity. Second, optimization may expand latch into a complete spare set; compare objects without adding unconfirmed composition. Third, another application’s latch parcel may be adopted; inspect request, model and shipment object rather than matching the part term alone. These concern component, rewritten scope and record attribution. A common model or highly scored logistics passage does not establish dispatch for this request, and the actual needed record cannot be supplied through more similar wording.
How to verify the setup
Ask what the request concerns, how parts are separated and what was sent, expanding actual references. Compare semantic, full-text and hybrid retrieval with identical questions, retaining component names under token limits rather than dispatched alone. Added latch records need current request and parcel checked, keeping sending distinct from customer receipt. This exercise creates no replacement order, arranges no carrier and verifies no fit or actual fault. Missing evidence stays pending rather than an inferred refusal to send because the search did not return a current dispatch record.
