What the documents look like
For product questions in JD POP seller operations, this page examines FastGPT retrieval. Compare the material received with the sources used in the answer. The examples are hypothetical.
Constraints at the retrieval step
A new JD POP product sheet says, “Device main unit; connection cable selected separately.” Retrieval must distinguish the main item from an option and preserve the separate-selection condition. Matching cable alone does not establish standard inclusion. Inspect candidates for main-unit and cable terms, then compare the three modes with a package-contents question. A model or interface absent from the original needs corresponding material, without completion from the product name.
Configuration and implementation checks
| Documented item or implementation check | Material and condition | Evidence action |
|---|---|---|
| Source scope (implementation check) | Separate product information and user feedback | Feedback does not supply the original configuration. |
| Search modes: semantic, full-text, hybrid | Main-unit and complete package question | Compare retention of the separate-selection condition. |
| Citation token limit | Separate-selection and feedback contexts | Inspect trimming for a changed source role. |
| Minimum relevance | Inspect filtering under semantic search or reranking | A service record is not a complete specification. |
| Question optimization | Device-compatibility follow-up | Do not create a model from a fault record. |
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
A proposed warranty-service record states that a user reported a cable fault. If it is used as the original order’s sales configuration, the source role has been misplaced. Retain the service record, product sheet and final citation together. Also inspect whether token trimming removed the reported-feedback context: an isolated fault statement may become an asserted product condition. Nearby source wording does not establish verified order contents. A third error turns the cable complaint into a confirmed cause of failure. Seek an applicable inspection finding and distinguish a service-entry statement, observed condition and causal conclusion. A shared accessory name does not establish cause or responsibility.
How to verify the setup
The cable model and supported-device list are absent. Before optimizing a follow-up asking which device this cable fits, establish that an identified cable exists in the input. If optimization invents a model from the fault record, retain both question versions and identify the unsupported addition. Repeat after obtaining the explanation and trace new citations, separating document additions from settings changes. Check minimum relevance under semantic or reranking conditions; a leading service record does not establish complete compatibility evidence.
