What the documents look like
For product questions in Brand repair services, this page examines FastGPT vector indexes. A post-replacement service record cannot directly redefine the original product version. The examples are hypothetical.
Constraints at the vector indexes step
A proposed brand-service product packet says the original panel is a basic version, records replacement with a textured panel and leaves the post-replacement state awaiting review. A question about purchase-time texture needs the original version, not just later service. An entry turning replacement information into factory-textured configuration would change both time and state. Preserve original description, repair action and review status rather than merging stages of one main unit into a timeless specification. Pending review also cannot establish that replacement itself never occurred.
Configuration and implementation checks
| Original-data/index check | Specific subject relationship | Acceptance action |
|---|---|---|
| Original version | Basic panel | Do not infer original configuration from repair. |
| Service stage | Textured panel replacement | Retain later action. |
| Target timing | Purchase question may target post-repair text | Inspect original stage. |
| Review state | Awaiting review | Do not change to verified. |
| Added-evidence adoption | New delivery or review material | Check unit version and actual citations. |
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, a replacement attribute may become original configuration; inspect purchase-version or delivery material. Second, a basic-version entry may target a post-repair record; inspect target stage and service subject. Third, an index may omit pending review and the answer claim verified replacement; inspect an actual review record. These require historical configuration, target timing and result evidence respectively. A common main-unit name cannot complete the checks, and one service event cannot establish that every product was upgraded or that the current result has passed verification.
How to verify the setup
Acceptance should ask what the original note states, what the repair records and where review stands. Preserve temporal relationships in entries and citations. Purchase-time questions need applicable original material rather than a repair-derived configuration. After delivery or review records are added, inspect unit identity and version before processing and mapping checks, then compare the same questions. Several entries targeting replacement still provide no original purchase specification. Traceable retrieval cannot replace the separate business fact of whether an actual review was performed or its result confirmed.
