What the documents look like
For product questions in General export declarations, 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 export invoice test can state, “Display-rack components, delivered disassembled.” This supports a product designation and delivery form. The rack noun alone does not establish an assembled finished item. Inspect candidates for components and disassembled, then compare the three search modes using the complete document-form question. Keep both qualifications attached to the product. This reading test does not assign a classification code or make a customs-declaration decision from retrieval.
Configuration and implementation checks
| Documented item or implementation check | Material and condition | Evidence action |
|---|---|---|
| Source scope (implementation check) | Inspect overall form separately from packed sub-items | The two records do not supply an assembly list. |
| Search modes: semantic, full-text, hybrid | Components, disassembled and the complete form question | Compare qualifying wording across retrieval modes. |
| Citation token limit | Keep the disassembled condition attached to the rack | Trimming must not leave only the product name. |
| Minimum relevance | Inspect filtering under semantic search or reranking | A score is not a document-classification conclusion. |
| Question optimization | Follow-up about delivery form | Retain components without assuming assembly. |
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 packing list separately lists an accessory bag. Inspect the level described by each document: the invoice states the overall form, while the list identifies a packed sub-item. These statements need not contradict each other and do not supply a complete assembly list. Retain original wording and file identity, checking whether a returned passage is a product description or packaging entry. Record any token-limit omission that leaves only the rack name without its disassembled condition.
How to verify the setup
Component dimensions and manufacturing details were not supplied. Neither the rack nor accessory-bag name provides those parameters. Until corresponding technical material is obtained, preserve the missing sources without expanding them into established specifications. Repeat the question after supplementation and trace the added originals and citations. Optimization should retain components and disassembled. Check relevance under its applicable conditions, without replacing examination of document scope with a score or snippet count.
