What the data for this category looks like
Renovation and decoration marketing content data primarily comes from financial institution renovation installment product documents, official case libraries of partner renovation companies, material parameter manuals, construction specification documents, marketing copy templates, and local store service ledgers. Update cadences vary by content type: new renovation cases are updated monthly, material parameters are updated quarterly to align with supply chain adjustments, marketing copy is adjusted monthly for holiday events and promotion nodes, and installment product rules are updated quarterly per regulatory requirements. Document structure centers on single cases, with fields including floor plan, building area, material list, construction period, quotation range, supporting services, installment rates, and more. Units include square meters, yuan per square meter, days, and other professional engineering units.
What constraints these characteristics impose on knowledge base retrieval and recall
Single case documents are lengthy, containing multi-dimensional professional parameters and financial product rules. This easily leads to key information being split across segments, so retrieval and recall must retain complete associated parameter logic. The presence of multiple fields requires retrieval to match specified business fields, preventing irrelevant content from being recalled. Monthly and quarterly update cycles require regular full or incremental index triggers; otherwise, outdated cases, quotations, and installment rate information may be returned. Regional service content fields require retrieval to associate regional dimensions for filtering, ensuring recalled content aligns with local store service scope and local installment policies.
Configuration Settings
| Configuration Key | Recommended Value | Rationale |
|---|---|---|
Chunk Length | 800–1200 characters | Single renovation case documents are lengthy, to avoid splitting critical construction parameters and installment rate information |
Similarity Threshold | 0.72–0.85 | Content combining renovation and finance has high professional requirements, to filter low-match irrelevant documents |
Recall Count | Top 6 entries | Covers user needs for different floor plans, budgets, and installment rates, balancing information density and selection options |
PARSE_SPLIT_OVERLAP | 150–200 characters | Avoid splitting cross-paragraph material lists and construction processes, ensuring segment integrity |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Renovation and decoration documents often contain high-definition case images, leading to large single-file sizes; set a reasonable upper limit |
Incremental Index Trigger Frequency | 1 time per day | Marketing content and installment rules are updated frequently, daily synchronization ensures recall timeliness |
The parameter values provided on this page are common recommendations used as starting points for configuration. Actual values are affected by material format, data volume, and business rules. Each scenario requires individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Duplicate renovation case documents appear in retrieval results, and the number of indexed segments displayed in the interface does not match the estimated segment count at upload. Cause: No reasonable segment overlap parameter is set, leading to excessive overlap between adjacent segments, which triggers duplicate indexing logic.
- Symptom: Citation entries from knowledge base retrieval results are not displayed at the very bottom of the response as required. Cause: The fixed position configuration for knowledge base citations is not enabled, leading to chaotic citation placement.
- Symptom: Uploading documents larger than 1000 MB triggers an upload failure, returning a 413 status code. Cause: The
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, exceeding the configured file size upper limit.
How to Verify Successful Configuration
- Upload a single renovation case document containing high-definition images, confirm that the upload succeeds and parsing segments have no abnormalities.
- Initiate a retrieval containing keywords for floor plan, budget, and installment rates, check that the field matching degree and segment integrity of the recall results are correct.
- Manually trigger an incremental index once, view the index logs for any abnormal prompts about duplicate segments or upload failures.
- Verify the citation sources of retrieval results, confirm that only valid documents within the current configuration range are displayed, and that citation entries are shown at the very bottom of the response.
