Data Characteristics of This Category
Data for consumer electronics intelligent due diligence reports comes primarily from supply chain BOM lists, SKU parameter manuals, third-party quality inspection reports, new product launch announcements, and batch compliance documents. Update frequency adjusts based on product segment. During consumer electronics new product iteration cycles, supply chain data is updated weekly, and compliance documents are released with each batch.
Documents include structured fields and unstructured text. Structured fields cover product model, rated power, battery capacity, supply chain manufacturers, and more, with units such as watts, milliamp hours, millimeters, and others. Unstructured content mostly consists of product reviews, compliance explanations, and after-sales data.
Constraints on Vector Models and Indexing
Consumer electronics intelligent due diligence reports have a large number of structured parameters, uneven update frequencies, and batch-associated data. These factors create multiple constraints for the vector model and indexing workflow.
The vector retrieval process follows these steps: split documents, generate vectors, build indexes, then complete recall via similarity matching. Structured parameters require separate vector weight mapping to avoid confusion with the vector weights of unstructured review text. Frequently updated supply chain data requires indexes to support incremental synchronization, to avoid excessive time spent on full index reconstruction. Batch-associated SKU data must retain batch field associations in indexes, to ensure recall results match the corresponding production batch. Long text review reports and short parameter fields are mixed, so reasonable chunking rules must be set to prevent structured parameters from being split across different chunks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Consumer electronics BOM lists and quality inspection reports are often hundreds of MB per single file. This value covers most scenarios |
chunk_size | 800–1200 characters | Consumer electronics documents mix structured parameters and long text reviews. This range prevents structured fields from being split |
VECTOR_SIMILARITY_THRESHOLD | 0.75–0.85 | Parameter differences between the same model and different batches must be distinguished. This threshold range filters low-correlation recall results |
RECALL_TOP_K | Top 10 entries | Consumer electronics due diligence requires balancing core parameters and associated review content. 10 entries covers most retrieval needs |
INDEX_INCREMENTAL_SYNC | Enabled | Supply chain data is updated weekly. Incremental synchronization reduces resource consumption from full index reconstruction |
PARSE_FIELD_WEIGHT | Set structured field weight to 1.5, unstructured field weight to 1.0 | Structured parameters have higher requirements for due diligence accuracy, so their vector retrieval weight should be increased |
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 targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: When uploading consumer electronics BOM files larger than 10 MB, some chunk vectorization fails, and the interface displays the
500error code for "vector generation timeout". Cause:chunk_sizeis not adjusted to fit long structured tables, causing some chunks to exceed the model's maximum input length. Retrying does not resolve the root issue. - Symptom: After server restart or version update, existing consumer electronics knowledge bases are in the "not ready" state, and automatic index reconstruction cannot be triggered. Manual operation via the edit page is required. Cause: The
INDEX_AUTO_REBUILD_ON_RESTARTconfiguration is not enabled. It is disabled by default, so automatic index synchronization after restart does not function. - Symptom: After updating to versions 4.9–4.10, searches for existing consumer electronics knowledge bases return no results, with an empty list. Cause: The vector index format changes after the version update, and existing indexes have not completed automatic migration.
How to Verify Correct Configuration
- Upload a single 1500 MB consumer electronics quality inspection report, check that the upload progress bar completes normally, and no prompts for "vector generation failure" appear.
- Retrieve the parameter fields of a specified SKU, verify that the recall results include structured data for the corresponding batch, and that structured results have higher weight than unstructured review content.
- Modify one supply chain manufacturer field, wait 10 minutes, then retrieve to confirm that the index has completed incremental update, with no manual trigger for reconstruction required.
- Check system operation logs to confirm there are no error messages for "chunk splitting exception" or "vector index sharding failure".
