Deployment and Upgrade for White Goods Industry Research

What the data for this category looks like

White goods industry research report data comes from securities firm home appliance industry research teams, China Household Electrical Appliances Association, and offline retail monitoring institutions. Core retail data is updated monthly. Full-category shipment volume reports are updated quarterly. Industrial trend white papers are released annually. Document structures include core operating indicators, segmented category breakdown, online/offline channel share, policy impact analysis, and other modules. Fields include publishing institution, publishing date, shipment volume (unit: ten thousand units), terminal average price (unit: yuan per unit), year-over-year growth rate, and more. Some reports include segmented brand performance data for enterprise-side segments.

What constraints these characteristics impose on deployment and upgrade

The different update frequencies of monthly retail data and quarterly shipment reports require configuring scheduled tasks for multi-source data synchronization during deployment. Separate pull cycles are set for different data sources. Documents contain split multi-module content. Segment parsing configuration must retain module association to avoid cross-module context breaks. Differences in units for segmented fields require unifying field mapping rules before vector database ingestion. This avoids unit confusion during retrieval. Annual white papers have longer length. Adjust segment length to adapt to long document parsing. During upgrades, compatibility must be maintained for newly added brand segmented fields. This prevents the existing vector database from failing to recognize new fields.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Adapt to long document parsing needs of annual industrial white papers, avoid mid-parsing timeout interruptions
`UPLOAD_FILE_MAX_SIZE`	`2000 MB`	Cover maximum size of a single annual research report, allow full upload of complete industrial data
`PARSE_CHUNK_SIZE`	`1000–1200 characters`	Retain complete logic of research report segmented modules, avoid context breaks after splitting
`Number of retrieved results`	`Top 8 results`	Cover retrieval needs for multiple segmented white goods categories, avoid missing segmented brand data
`Similarity threshold`	`0.72–0.78`	Filter non-home appliance research reports across categories, accurately match white goods-related content
`Number of re-ranked returned results`	`Top 3 results`	Reduce redundant re-ranked results, balance retrieval accuracy and response speed

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Misconfigurations

A Cannot read properties of undefined (readi error occurs when calling the PDF parsing tool. The cause is failure to correctly configure the dependency path of the pdf-marker plugin in the 4.9.0 version deployment environment, leading to plugin initialization failure.
After uploading a large annual research report, retrieval results are empty. Backend logs show parse timeout. The cause is failure to adjust the PARSE_FILE_TIMEOUT_SECONDS parameter, resulting in system interruption of long document parsing due to timeout.
After upgrading the version, the original research report retrieval function cannot be triggered normally. The cause is failure to synchronously update the field mapping rules of the vector database, leading to incompatible field structures between new and old versions.

How to Verify Proper Configuration

Upload a small white goods monthly research report. Check the parsed text segments to confirm the segment logic matches the PARSE_CHUNK_SIZE configuration.
Enter a search keyword for air conditioner shipment volume. Verify that the number of returned results matches the Number of retrieved results setting.
Check container runtime logs. Confirm there are no parse timeout related errors to verify the PARSE_FILE_TIMEOUT_SECONDS configuration effect.
After upgrading the version, import an old version research report. Confirm that retrieval results can be returned normally to verify field mapping and version compatibility.
