What the Data for This Category Looks Like
Data for this category comes from multiple types of business documents at electroplating plants and hardware surface treatment workshops. These documents include bath analysis records, process parameter cards, fixture records, film thickness adhesion reports, hazardous waste management ledgers, and wastewater monitoring records. Data sources cover customer surface treatment specifications, bath test results, rectifier operation data, and online water quality monitoring results. Updates occur per bath cycle, per shift, or according to fixed monitoring cycles. Each individual document contains fields such as bath number, test indicator values, operating parameters, and compliance records. Some indicators have clear units: current is measured in amperes, and concentration is measured in grams per liter.
What Constraints Do These Characteristics Impose on Knowledge Base Retrieval and Recall
The data characteristics of this category impose multiple constraints on the retrieval and recall process. The high-frequency, scattered update rhythm requires incremental recall to avoid time-consuming full index rebuilds. Multi-source heterogeneous document formats and process parameters with units require retrieval matching to associate fields and unit correspondences, rather than relying solely on keyword matching. Business correlation is strong for each bath cycle and batch. Retrieval results must prioritize associated documents such as fixture records and bath analysis reports from the same batch to ensure review logic consistency. Compliance documents must retain full batch association information, and retrieval results must not omit key compliance record fields.
Configuration Settings
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Meets precision requirements for matching electroplating process parameters and compliance records, filters low-relevance non-process documents |
limit | Top 8–12 results | Covers the number of associated documents for single-batch bath, process, and compliance records, avoids context overload |
searchMode | fullTextRecall | Adapts to multi-source heterogeneous document structures, supports mixed matching of parameter values and text descriptions |
usingReRank | Enabled | Reorders initial recall results by business relevance, prioritizes displaying associated documents from the same batch |
datasetSearchUsingExtensionQuery | Enabled | Automatically expands retrieval keywords, supplements unit-related terms for process parameters to improve matching accuracy |
collectionIds | Collection IDs divided by business domain | Isolates surface treatment data from different workshops and categories, avoids cross-domain interference |
Three Common Configuration Mistakes
- Phenomenon: Irrelevant non-process documents frequently appear in retrieval results, or redundant internal index annotations are included. Cause:
collectionIdsis not configured to isolate datasets by business domain, or non-essential index field display is not disabled. - Phenomenon: The number of retrieval results is insufficient to cover the full review requirements for single-batch bath, process, and compliance records. Cause: The value of
limitis set too low, failing to retrieve associated documents such as fixture records and film thickness reports from the same batch. - Phenomenon: Page loading timeout or crash prompts appear. Cause: Incremental recall logic is not configured, full index rebuild occupies excessive system resources, or the
similarityvalue is set too high, resulting in too few initial recall results and subsequent timeout in the re-ranking stage.
How to Verify Proper Configuration
- Check the dataset's collection division configuration, confirm that
collectionIdsis bound to the current workshop's surface treatment business domain. - Run a retrieval with a specific batch bath number, verify that the number of returned results falls within the preset
limitrange. - Check the relevance of retrieval results, confirm that the matching accuracy meets the current business's review requirements.
- View the display order of retrieval results, confirm that associated documents from the same batch are displayed before historical data.
