What the data for this category looks like
Data sources for specialized chain industry research reports include chain format operation reports released by industry associations, store survey data from third-party retail consulting institutions, and excerpts from quarterly operation announcements publicly released by listed chain enterprises. Core data is updated quarterly. Dynamic data such as new store layout and regional price adjustments is updated monthly. Documents include modules such as store distribution tables, per-store per-square-meter efficiency statistics, supply chain cost proportions, and regional consumer profiles. Fields include unique identifiers such as store number, region code, per-square-meter efficiency unit, and store count.
What constraints these characteristics impose on deployment and upgrade
The multi-source mixed data of specialized chain industry research reports requires supporting batch import of third-party reports and public financial report excerpts during the deployment phase. Custom field mapping rules must be configured to adapt to unique fields such as store numbers and region codes. The combined quarterly and monthly update rhythm requires adding incremental synchronization scheduled tasks during the upgrade phase, to distinguish update frequencies between core data and dynamic data. The lengthy document structure and unique fields require adjusting parsing parameters during the deployment phase to avoid truncation of core information. Indexes must be created for unique fields in advance to improve retrieval accuracy.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Specialized chain industry research reports contain multi-region store data and supply chain tables, with higher parsing time than general documents |
UPLOAD_FILE_MAX_SIZE | 2048 MB | A single chain research report collection may include multiple quarters of store operation data, resulting in large file size |
maxContext | 10000–14000 characters | Full context of key fields such as per-square-meter efficiency and store density must be retained to avoid truncation of core information |
Recall Count | Top 8 results | Covers chain store data from different regions and formats, to avoid overly concentrated results |
Similarity Threshold | 0.78–0.82 | Filters general retail content to accurately match unique keywords of chain formats |
SYNC_INCREMENTAL_INTERVAL | 24 hours | Matches the quarterly research report update cycle, synchronizes the latest store dynamic data daily |
The parameter values provided on this page are common 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 mistakes
- The symptom is a "field not indexed" error during retrieval. The cause is failing to add a vector database index creation script in the docker-compose configuration, and failing to create indexes in advance for unique fields such as store ID and region code.
- The symptom is a "mongoose version incompatible" log after starting the container. The cause is failing to lock dependency versions in package.json. The automatically installed mongoose version during container deployment does not match the version required by the application.
- The symptom is a "response timeout" prompt when viewing session details. The cause is failing to adjust the
PARSE_FILE_TIMEOUT_SECONDSparameter. The long document parsing timeout is not correctly captured by the system.
How to confirm configuration is complete
- Upload a local specialized chain industry research report document, view the parsed field list, and confirm that unique fields such as store per-square-meter efficiency and region code are correctly identified.
- Initiate a retrieval request containing keywords related to regional chain stores, view the number and matching degree of returned results, and confirm that the recall rules and similarity threshold configurations take effect.
- View the container running logs, confirm that the daily incremental synchronization task starts at the scheduled time, and there are no parsing failure or synchronization exception logs.
- Enter the session log page, view the response status of the most recent retrieval, and confirm that no timeout or format error prompts appear.
