What the documents look like
For product questions in Amazon FBA preparation, this page examines FastGPT hybrid retrieval. Compare the material received with the sources used in the answer. The examples are hypothetical.
Constraints at the hybrid retrieval step
The proposed FBA inbound-plan attachment lists smart bracelets, one hundred pieces and a small size category. These support a reading of the supplied stocking description. After marking the original name, quantity and size wording, compare fused candidates with the reranked result for the same item. A size question should not lose its size passage behind a quantity-only candidate. Retain the cited wording instead of expanding “small” into dimensions that the source never supplied.
Configuration and implementation checks
| Item or implementation check | Input or applicable condition | Traceable check |
|---|---|---|
| Fused candidates | Bracelets, one hundred pieces and small size category | Preserve the association between the three details. |
| Complete question | Electronic-product category and fragile-handling note | Check that the answer preserves both source roles. |
| Minimum relevance | Inspect filtering under actual semantic or reranking conditions | Inspect recall first if the carton label is missing. |
| Citation token limit | Original category and handling statements | Avoid isolated terms with unidentifiable sources. |
| Missing-source retest | No special-packaging instructions supplied | A fragile label does not supply materials or packing layers. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Hybrid retrieval | Vector and full-text results use RRF fusion. |
| Reranking | Reranking reorders candidates using the full question. |
Minimum relevance | Filtering applies to semantic search or reranking. |
Citation limit | Citation content is limited by tokens. |
Question optimization | Compare subjects and restrictions after optimization. |
Three common errors
“Electronic product” in the inbound plan and “fragile item” on the carton label can both be true. They are not automatically opposing evidence. Distinguish product category from handling information and keep both originals traceable. If the label is missing from candidates, inspect its recall first. When both are present, check whether reranking encourages a handling note to be described as a product category or citation trimming leaves a short term without a recognizable source.
How to verify the setup
The existing bracelet plan lacks special-packaging instructions. A “fragile” label cannot create a complete packing procedure. Inspect whether the answer invents specific materials or packing layers, and obtain the relevant instructions from their actual source. Use the same packaging question before and after supplementation, retaining candidates, order and citations to establish where a new requirement came from. Retrieval or reranking scores cannot replace reading the packaging requirement in its original context. Record the missing packaging instructions separately from the available carton label. A handling note does not supply a complete procedure. If added material covers only part of the question, the answer should preserve that limited scope instead of describing a full packing plan.
