Data Overview for This Category
This category of data primarily comes from daily deliverables of architects, technical leads, and platform development teams. These deliverables include technical documents, architecture diagrams, capacity assessment reports, technical review minutes, and similar materials. Most are outcomes finalized after constraint collection, solution trade-off demonstration, and closure of review feedback. Data sources cover historical traffic data, service topologies, monitoring metrics, and business growth plans. Update frequency is once per month or alongside major requirement iterations. Documents typically include fields such as constraints, cross-service boundary rules, resource thresholds, and review opinions. There is no unified fixed format. Some documents exist as plain text, drawing files, or structured tables.
Constraints Imposed on Knowledge Base Retrieval and Recall
The characteristics of this category of data impose multiple constraints on retrieval and recall. First, document types include plain text, drawing files, and structured tables. Multi-format content parsing must be supported to avoid missing key information such as architecture diagram topologies and capacity assessment thresholds. Second, data updates accompany major requirement iterations, and incremental synchronization frequency is not fixed. Knowledge base refresh must support on-demand triggering. Third, the core of documents consists of constraints, cross-service boundary rules, and review opinions. Core work includes constraint collection and solution trade-offs. Retrieval must prioritize matching technical decision content for operations duty scenarios, and filter out generic business description content. Finally, time-series monitoring data and structured service topologies require targeted recall rule configuration to ensure extracted information meets operations scenario requirements.
Configuration Guidelines
This document is written based on the configuration logic of FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Semantic similarity threshold for matching professional texts such as architecture solutions and review minutes, to avoid recalling irrelevant generic operations content |
limit | Top 8 entries | Controls the number of knowledge base entries recalled per single query, adapting to the need to quickly locate technical solutions during operations duty scenarios |
usingReRank | Enabled | Re-ranks recalled architecture documents to prioritize displaying technical review opinions or constraint conditions most relevant to the current operations ticket |
collectionIds | Configured by business domain | Distinguishes between different types of knowledge bases such as technical solution libraries and monitoring metric libraries, to avoid cross-domain recall interference |
searchMode | Semantic retrieval | Adapts to professional semantic matching requirements for architecture documents, replacing pure keyword retrieval |
datasetSearchUsingExtensionQuery | Enabled | Expands operations-related keywords based on the original question, improving recall rates for professional content such as capacity assessments and service topologies |
Three Common Misconfigurations
- Phenomenon: A 60-second timeout error occurs when switching knowledge base indexes. Cause: No reasonable chunking rules are configured for large-volume drawing files or structured tables in architecture documents, leading to data loading timeout during index construction.
- Phenomenon: Markdown format content cannot be rendered in context references. Cause: Multi-format parsing configuration is not enabled, only plain text content is recalled, and Markdown syntax in architecture diagram descriptions and review minutes is not supported.
- Phenomenon: Queries cannot reference files from a specified knowledge base, or content from non-target knowledge bases is recalled first. Cause: The
collectionIdsparameter is not configured correctly, or no knowledge base priority rules are set, leading to retrieval scope covering irrelevant business knowledge bases.
How to Verify Successful Configuration
- Manually trigger a retrieval targeting an architecture solution, and check if recalled results prioritize technical constraints or review opinions relevant to the current operations ticket.
- View knowledge base index construction logs to confirm no timeout errors occur, and that index update frequency matches business requirements.
- Test retrieval results for different types of documents such as architecture diagrams and capacity assessment reports, confirming that multi-format content can be properly recalled and displayed.
- Adjust the
similarityparameter range, verifying that the relevance of recalled results meets expectations for operations duty scenarios.
