What data for this category looks like
Duty-free marketing data comes from four main sources: official product catalogs of duty-free operators, offshore duty-free policy announcement documents, offshore shopping user forms from partnered financial institutions, and parameter databases for duty-free installment products. Product SKUs and installment product data are updated and synchronized weekly. Policy documents are adjusted irregularly to meet regulatory requirements. User-submitted form data is stored in the database in real time. Each product document includes fields such as product name, duty-paid price, duty-free selling price, single purchase limit, and applicable offshore crowd scope. Field units use a standard set of RMB yuan, pieces, and person-times. Policy documents include policy effective periods, applicable regions, and detailed quota restrictions.
What constraints these characteristics impose on forms and interactions
The weekly update requirement for product SKUs and installment products means product and installment product selection components in forms must connect to real-time synchronized data sources. This prevents users from selecting discontinued products or halted installment products. The irregular adjustment requirement for policy documents means policy prompt pop-ups in interactions must support quick background updates, without requiring changes to front-end code logic. The real-time storage requirement for user-submitted form data means forms must add real-time verification logic. This includes pre-verification of single shopping quotas, offshore identity information, and installment qualifications, to reduce invalid submissions. The unified field unit requirement means unit prompts must be added to form input fields to prevent users from entering incorrect numerical units. Verification feedback must also clearly display the unit rules used for validation.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Duty-free marketing content typically includes product details, policy details, and installment rules. This range covers context needs for most scenarios, and avoids exceeding model input limits |
FORM_FIELD_MAX_LENGTH | 200 characters | Consultation and remark fields in duty-free forms usually do not require long input. This length filters invalid long-text submissions |
RECALL_TOP_K | Top 6 entries | Duty-free policies and product information have standardized wording. Too many recall results will cause redundant context. 6 entries covers core information needs |
SIMILARITY_THRESHOLD | 0.75–0.85 | Duty-free related documents have strong semantic consistency. This threshold filters low-relevance recall results and improves interaction accuracy |
UPLOAD_FILE_MAX_SIZE | 100 MB | Single files such as duty-free policy documents and product manuals usually have small sizes. This setting prevents import failures caused by overly large files |
FORM_SUBMIT_TIMEOUT | 10 seconds | Duty-free forms include real-time quota verification and qualification validation logic. 10 seconds covers verification and submission delays for most network environments |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
maxContextover-limit interception is not configured. When a user submits excessively long marketing copy or consultation content, the model input upper limit error is triggered directly, returning error code413. This occurs because context length verification is not set in advance, and the model's native error message is exposed directly to users.- Form variables are not correctly bound in the knowledge base search card. This causes the system to fail to match exclusive information for duty-free products or policies during retrieval. This occurs because field values such as offshore region and product type submitted in the form are not passed as search parameters to the search node.
- Chunking parameters are not adjusted when importing PDF documents to the knowledge base. This causes long paragraphs in duty-free product manuals to be incorrectly split, resulting in incomplete recalled policy clauses. This occurs because chunking length is not adjusted for the long-text structure of duty-free documents, leading to loss of key information.
How to confirm configurations are complete
- Submit test text that exceeds the
maxContextlimit length, confirm the system displays a preset over-limit prompt instead of a native error message. - Select a discontinued test product or halted installment product in the form, confirm the component automatically filters this option and prevents selection.
- Upload a single test file with a size exceeding
100 MB, confirm the system displays a file too large prompt and blocks import. - Enter a non-RMB numerical value in the form, confirm the system displays a unit error verification prompt and blocks submission.
