What the data for this category looks like
Packaging and printing investment research data mainly comes from industry association monthly operation reports, technical parameter documents of printing equipment manufacturers, quotation sheets of upstream and downstream raw material suppliers, annual reports of listed companies, and national standard documents for printing quality. The update rhythm varies significantly: raw material quotes are updated daily, industry operation reports are released monthly, and process standard documents are revised annually. Document formats include structured tables such as production capacity and quotation details, long-text process specifications, and structured parameter lists. Core fields include grammage, color code, printing format, and delivery cycle, with corresponding units of gsm, color code, mm, and day.
What constraints these characteristics impose on deployment and upgrade
Since the data includes multi-format structured tables and long-text process documents, plugins that support multi-format parsing must be configured during deployment, and field and unit retention rules must be adapted. Frequently updated raw material data requires scheduled incremental synchronization tasks to be deployed, to avoid excessive resource usage from full synchronization. During upgrades, the field mapping configuration of original parsing rules must be retained, to prevent the index keys of structured data from being reset. The compatibility of the new version's parsing plugin with printing industry standard documents must be verified, to avoid missing parsed fields. The investment research scenario has high requirements for data accuracy, so a data verification link must be configured during deployment, to ensure that synchronized fields match the original data.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Packaging and printing process documents are usually long and include complex table parsing, so sufficient timeout is needed to avoid parsing interruptions |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Documents such as industry reports and annual reports of listed companies have large file sizes, so large file upload support is required |
maxContext | 800–1200 characters | Core paragraphs of investment research documents are mostly process parameters or quotation details, and adapting to this length can retain complete field information |
Recall count | Top 8 entries | Packaging and printing investment research needs to cover multi-dimensional data including raw materials, equipment, and processes, and sufficient recall volume can improve matching accuracy |
Similarity threshold | 0.72–0.85 | Distinguish similar printing format parameters and color code values, avoid irrelevant content from being recalled |
Scheduled Sync Trigger Interval | 00:00 daily | Matches the daily update rhythm of raw material quotes, ensuring data timeliness |
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, and it is recommended to test on your own samples before finalizing.
Three common errors
- Symptom: After upgrading from 4.8.17 to 4.8.18, historical knowledge base content cannot be retrieved with the same query. Cause: The field mapping configuration of the original parsing rules was not retained during the upgrade, causing the index keys of structured data to be reset.
- Symptom: The model list does not update after modifying config.json during docker-compose deployment. Cause: The corresponding service container was not restarted, so the configuration file was not reloaded.
- Symptom: An error is returned when clicking the knowledge base module, with a 500 status code. Cause: The local file storage path is not configured in the default settings, causing knowledge base files to fail to be read normally.
How to confirm the configuration is complete
- Upload a packaging and printing quotation sheet that includes grammage and color code fields, check if complete fields and corresponding units are retained after parsing.
- Trigger a scheduled synchronization task, check if the synchronization log shows that the latest raw material quotation data was successfully pulled.
- Restart the service after modifying configuration items, verify that the model list on the interface is updated synchronously.
- Initiate a retrieval request that includes printing format parameters, confirm that the retrieval results include matching structured data entries.
