What the data for this category looks like
Black home appliance research report data mainly comes from public reports from industry associations, official technical documents from leading brands, and analysis content released by third-party market research institutions. Update rhythm fluctuates with new product launches and industry policy adjustments. There is no fixed cycle, but core category reports are updated quarterly. Documents take structured tables as core components, including fields such as product SKU, energy efficiency rating, rated power, market selling price, sales volume proportion, and more. Power unit is kilowatt-hours per year, selling price unit is yuan. Some reports include competitor parameter comparison matrices. The word count of single documents varies widely.
What Constraints These Characteristics Impose on Deployment and Upgrade
The high proportion of structured tables, clear field units, and frequently used retrieval parameters in black home appliance research reports impose multiple constraints on the deployment and upgrade process. The parsing link must adapt to table structures, otherwise core parameter comparison information will be lost. Field standardization configuration must match the units and field names in the reports, to avoid unit confusion or field mismatch issues during retrieval. The non-fixed update rhythm requires synchronization configuration to support flexible adjustment of trigger cycles, to adapt to temporarily released new product reports. Frequently used retrieval fields focus on product parameters, so recall rules must be configured specifically to improve retrieval accuracy.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Black home appliance research reports contain a large number of structured tables. Enabling this option can fully retain the row and column structure and field information of tables |
UPLOAD_FILE_MAX_SIZE | 200 MB | Single black home appliance research reports usually come with multiple high-definition charts. A larger upload threshold allows complete import of full documents |
RECALL_FIELD_WHITELIST | ["SKU", "energy efficiency rating", "rated power", "selling price"] | These are frequently used fields for users to retrieve black home appliance research reports. Limiting the whitelist can improve recall accuracy |
SYNC_CRON_EXPR | 0 0 2 * | Execute synchronization at 2:00 AM daily. This adapts to the quarterly update rhythm of core categories, and also covers temporarily released new product reports |
RERANKER_TOP_N | Top 6 entries | Black home appliance research reports have dense parameters. Around 6 reranked results can cover core comparison dimensions |
MAX_CHUNK_SIZE | 800–1200 characters | Table paragraphs in reports are relatively long. A moderate chunk size can retain contextual connections and avoid parameter splitting breaks |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing.
Three Common Mistakes
- Scenario: After importing a black home appliance research report knowledge base in JSON format, the system's optional knowledge base list is empty by default, and manual reconfiguration is required. Cause: The
ENABLE_JSON_KNOWLEDGE_BASE_AUTO_PARSEparameter is not enabled. For versions 4.8.22 and earlier, this parameter is disabled by default, causing JSON metadata to not be automatically identified and loaded by the system. - Scenario: Calling the Reranker model returns a permission error, and rearrangement of report content cannot be completed. Cause: The
RERANKER_ACCESS_TOKENparameter is not filled in correctly. A valid access token was not obtained from the corresponding model service provider, or the token is not bound to the calling permission for the corresponding model. - Scenario: The debug panel of the workflow orchestration does not display the output content of code running steps. Cause: The
WORKFLOW_DEBUG_SHOW_STEP_OUTPUTparameter is not enabled, or the current workflow is not correctly bound to the dependency environment of the code execution node.
How to Verify Successful Configuration
- Upload a single black home appliance research report containing structured tables. Check if the parsed document retains the row and column structure of the table to confirm the table parsing configuration is effective.
- Manually trigger a knowledge base synchronization. Check if the preset frequently used retrieval fields are displayed in the synchronization log to confirm the field whitelist configuration is correct.
- Start the workflow debugging process. Check if the code running steps display the corresponding output panel to confirm the debug display parameter is enabled.
- Enter a retrieval term targeting specific parameters of black home appliances. Check if the recall results match the target fields to confirm the recall configuration meets expectations.
