What the documents look like
For procurement in General export declarations, this page examines FastGPT vector indexes. Check indexes against distinct material, finish and supplier-introduction evidence. The examples are hypothetical.
Constraints at the vector indexes step
A proposed export-procurement packet describes an iron base, a copper-like appearance and a supplier accepting metal-product enquiries. A draft index says a copper base is confirmed for supply. The question asks whether the material is copper. Appearance establishes no substrate and a business introduction establishes no current supply; the material source states iron. Multiple question-oriented indexes may describe a block, but should retain its actual attributes. Borrowing finish and introduction wording cannot expand it into copper material plus a transaction commitment or establish any export qualification from the product description.
Configuration and implementation checks
| Original-data/index check | Specific subject relationship | Acceptance action |
|---|---|---|
| Substrate fact | Iron | Index must not override. |
| Color attribute | Copper-like | Do not make it copper material. |
| Introduction action | Accept enquiries | Do not make it order confirmation. |
| Older material page | Separate copper base | Inspect version and linked block. |
| Retest wording | Color and substrate | Inspect actual returns. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Embedding model | Knowledge bases associated with one search node must use the same embedding model. |
Original data and indexes | One original data block can have multiple indexes. |
Index content | Index wording should be complete and focused. |
Image indexes | Where image retrieval is used, inspect descriptions or image vectors. |
Version and result check | After a change, reuse questions to compare originals. |
Three common errors
First, copper-colored may become copper-made in the index; compare finish and substrate sources and inspect whether linked text retains iron. Second, accepting enquiries may become confirmed supply; inspect introduction role and current confirmation instead of treating general business wording as an order. Third, an index may target an older copper-base source while being treated as current; compare name, material and version. These concern attribute meaning, supply state and source identity. High relevance establishes no material fact, and an added index sentence cannot override the original data it claims to represent.
How to verify the setup
Ask about substrate, appearance and supplier wording separately, inspecting each actual reference with its index. After changes, repeat natural questions about color and material without guaranteeing exact distinction; actual returns must demonstrate what was retrieved. Appearance-only material leaves substrate unresolved, and failure to return evidence proves no false supplier statement. These are text tests without image or physical identification. Model and index changes still require source comparison, promise no procurement effect and replace no actual specification or supply confirmation for the intended current item.
