What Data for This Category Looks Like
Special steel investment research data comes primarily from public industry association reports, internal manufacturing enterprise ledgers, upstream alloy raw material markets APIs, and order announcements from downstream wind power and automotive sectors. Update frequencies vary significantly: industry research reports are updated quarterly, production and quality inspection data is updated daily, and raw material and downstream demand market data is refreshed hourly. The data includes structured fields such as grade, yield strength, and elongation, with units MPa and %. It also includes unstructured content like technical process documents and in-depth research report text.
What Constraints These Characteristics Impose on Deployment and Upgrade
The multi-tier update cycles and highly specialized structured fields of special steel investment research data impose multiple constraints on deployment and upgrade workflows. Teams must adapt to different synchronization periods for multi-source data, to avoid interruptions to real-time market data synchronization that harm retrieval timeliness. Specialized fields for structured data require custom parsing mappings during deployment. During upgrades, original field association rules must be retained to prevent structured retrieval failures in historical knowledge bases. Extended interfaces must also be reserved to support parameter field definitions for new special steel grades, avoiding format conflicts during future data access.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Special steel technical documents are usually lengthy with extensive process details; a longer timeout prevents parsing interruptions |
maxContext | 800–1200 characters | Special steel data contains specialized terminology and long-form parameter descriptions; an appropriate context length preserves complete parameter association information |
recall count | Top 8–12 results | Special steel investment research requires covering multi-dimensional data; a higher recall volume balances retrieval coverage for structured ledgers and unstructured research reports |
UPLOAD_FILE_MAX_SIZE | 500 MB | Large special steel process drawings and annual research report files have significant file sizes; this upload limit adjustment accommodates these files |
reranked return count | Top 3–5 results | Special steel data is highly specialized; retaining a small number of highly relevant results after reranking improves retrieval accuracy |
SYNC_INTERVAL | 300 seconds | Real-time market data requires regular synchronization; this interval balances timeliness and server load |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: After upgrading from version 4.8.17 to 4.8.18 or later, historical imported special steel knowledge base content cannot be retrieved. Cause: Original custom field mapping configurations were not retained during upgrade, leading to failed structured data retrieval associations.
- Phenomenon: After connecting SearXNG, test retrieval returns no results, and the backend returns a
500 Bad Gatewayerror. Cause: The special steel specialized term dictionary was not imported into retrieval filtering rules, leading to failure to correctly recognize specialized terminology. - Phenomenon: When configuring database connections and attempting to connect ClickHouse, data source binding fails. Cause: ClickHouse compatibility mode was not enabled in the FastGPT data source configuration, leading to protocol handshake failure.
How to Confirm Proper Configuration
- Upload a special steel production ledger file, check if all preset custom fields are fully retained after parsing, and verify that field mappings match configured settings.
- Trigger a real-time market data synchronization, check the sync status on the data source monitoring panel to confirm the sync interval matches preset requirements.
- Initiate an investment research retrieval query, check if returned results cover both structured parameter data and unstructured research reports, and confirm the recall count falls within the configured range.
- Perform a version upgrade rollback test to confirm the retrieval logic of the original knowledge base has not changed.
