What the data for this category looks like
The data for solid waste treatment financing daily reports mainly comes from financing record announcements of solid waste disposal projects published by local ecological environment departments, bidding and financing announcements on the national public resource trading platform, and daily financing dynamics compiled by industry associations. The update frequency is daily. Each daily report contains one or more project records, with a fixed document structure including these fields: project name, solid waste treatment subdivision type, financing amount, financing subject, fund provider, announcement release date, and project location. The unit of financing amount is ten thousand yuan, and date fields use standard Gregorian calendar format.
What constraints these characteristics impose on the "knowledge base retrieval and recall" link
The daily updated data source mandates setting up a scheduled incremental sync task for the knowledge base to avoid data lag behind the latest financing dynamics. Fixed structured fields mandate field-level precise matching in the retrieval link. For example, filter recall results by "solid waste treatment subdivision type" and "announcement date" to avoid mixing in financing projects from unrelated categories. The numeric attribute of financing amount and the time range attribute of date require the retrieval node to support filtering rules for numeric ranges and time ranges, to adapt to user query needs for specific amounts or time periods of financing projects. Short individual records paired with large batch entry volumes require optimizing recall sorting logic to prioritize fields matching user core query terms.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Knowledge Base Incremental Sync Cycle | 2:00 AM daily | Matches the daily update rhythm of solid waste treatment financing daily reports to avoid data delay |
Retrieval Recall Count | Top 10 entries | Individual daily report records are short, and there are many batch entries. 10 entries can cover users' core query needs |
Similarity threshold | 0.75-0.85 | Precise matching is required for the solid waste treatment subdivision type field. A threshold that is too low will mix in financing records from unrelated categories |
Text Chunk Size | 800-1200 characters | Individual financing project records have a clear structure. The segment length adapts to complete reading of structured fields |
Field-level Retrieval Switch | Enabled | Supports filtering by fields such as "solid waste treatment type" and "announcement date" to improve recall accuracy |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Individual daily report documents have a small volume. 300 seconds is sufficient for parsing to avoid timeout errors |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After upgrading FastGPT to version 4.8.20, an error
text index required for $text queryis returned when executing the knowledge base retrieval node. Cause: The full-text index of the knowledge base was not rebuilt after the upgrade, causing the retrieval to fail to call the text index matching rules. - Phenomenon: When configuring a
Knowledge base searchnode in a workflow and using variables to reference the knowledge base, an empty result is returned after invocation. Cause: The variable corresponding to the knowledge base ID was not configured in the workflow's startup parameters, or the variable format does not meet system requirements. - Phenomenon: When batch importing solid waste treatment financing daily report documents, some structured fields are not extracted correctly. Cause: The structured field recognition switch for knowledge base parsing was not enabled, causing the document to be processed only as plain text segments.
How to confirm the configuration is complete
- Execute a manual sync task, check whether the knowledge base update time matches the release time of the latest daily report, and adjust the incremental sync cycle to meet requirements.
- Initiate a test query that includes a specific solid waste treatment type and date range, verify whether the recall results contain eligible projects, and adjust the similarity threshold and number of recalled entries.
- View the workflow variable configuration page, confirm that the variable referenced by the
Knowledge base searchnode is correctly bound to the startup parameters, and verify that variable delivery is effective. - Check the knowledge base parsing logs, confirm that all imported daily report documents have been parsed without timeouts or format errors, and adjust the
PARSE_FILE_TIMEOUT_SECONDSparameter to adapt to document volume.
