What the documents look like
For after-sales questions in Letter-of-credit documents, this page examines FastGPT retrieval. Retrieve consignee, notification-party and amendment text by their distinct document roles. The examples are hypothetical.
Constraints at the retrieval step
A proposed document-support packet asks to verify a consignee alias, reports a corrected notification-party name and lists related pages as attachments without their contents. The current question asks whether the consignee is resolved. Retrieve field role and pending state together. A name correction for one party cannot answer for another, and an attachment list supplies no amended wording. Compare alias, notification-party and full questions for candidate coverage. This reading exercise introduces no actual documentary requirements or bank-acceptance judgment and cannot decide a real amendment outcome from the proposed snippets.
Configuration and implementation checks
| Material check | Conditions in this test | Implementation evidence |
|---|---|---|
| Field role | Consignee and notify party | Retain candidate headings. |
| Enquiry state | Alias unresolved | Do not rewrite as known error. |
| Attachment visibility | List without contents | Inspect actual reference. |
| Mode comparison | Same question across three modes | Compare source fields. |
| Added amendment | Current enquiry and version | Do not use another transaction. |
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
First, a notification-party result may answer for the consignee; inspect field heading and original candidate. Second, optimization may turn an alias pending verification into an incorrect name; compare question strength because unresolved evidence is no established error. Third, an attachment title may become supposedly returned amendment text; inspect actual candidate and reference coverage. These concern role, question status and visible contents. Document quantity, relevance or fluent output does not establish a current correction without the actual linked material and its appropriate subject.
How to verify the setup
Ask which party changed, what remains pending and which attachment text is available, reading returned originals sentence by sentence. Compare semantic, full-text and hybrid modes with field headings retained. Token-limited references also need role and state together. Added consignee pages require current enquiry and version checks, avoiding another transaction’s names. This exercise modifies no documents, presents nothing and decides no conformity. Missing attachments require scope and transfer investigation rather than an inferred refusal or acceptance, with actual business outcomes remaining dependent on separate applicable evidence.
