Vector Models and Indexing for Cosmetics Financial Report

What the Data for This Category Looks Like

The financial report data of publicly listed cosmetics companies is sourced exclusively from publicly disclosed regular filings, including quarterly, semi-annual, and annual reports. Updates follow fixed schedules: quarterly, semi-annual, and annual. Each individual report includes standard modules such as core financial metrics, product line revenue breakdowns, channel sales share, and research and development expenditure details. Fields include operating revenue, operating costs, gross margin, R&D expense ratio, and more. Common units are Chinese yuan, ten thousand yuan, and percentage. Some companies include written notes on SKU iterations and brand matrix layout.

Constraints Imposed on Vector Models and Indexing

The mixed structured and semi-structured nature of cosmetics financial reports creates multiple constraints for the vector model and indexing workflow. First, reports contain both numeric fields such as revenue and gross margin, and text fields such as product line descriptions. Generic vector models cannot reliably preserve the precise semantic meaning of numeric fields. This requires a dedicated numeric encoding branch in the configuration. Second, text lengths vary widely across modules, ranging from a few dozen characters to hundreds of characters. This can cause loss of cross-module related information during segmentation processing. Fixed update frequencies and bulk data import requirements mean the index must support incremental update logic. This reduces computing resource consumption caused by full index rebuilding. Field naming conventions differ slightly across different companies’ financial reports. This requires the index configuration to support custom field mapping rules, to align with unified retrieval and matching standards.

Configuration Parameters

Configuration Item	Recommended Value	Rationale
`chunk_size`	800–1200 characters	Accommodates the mixed length of long text modules and short fields in cosmetics financial reports, avoids context fragmentation
`chunk_overlap`	100–150 characters	Preserves related information between adjacent segments, covers cross-module semantics of product line revenue and channel share
`index_type`	`HNSW`	Balances recall efficiency and retrieval accuracy for fast retrieval of bulk financial report data
`retrieval_top_k`	Top 8–12 results	Covers retrieval needs across multiple modules, avoids missing relevant information about detailed product lines
`similarity_threshold`	0.75–0.85	Filters low-relevance report fragments, aligns with the mixed multi-field retrieval and matching logic
`enable_incremental_index`	Enabled	Adapts to fixed-frequency bulk data imports, reduces resource consumption from full index rebuilding

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

Three Common Misconfigurations

Symptom: A 503 error is returned after startup, with a prompt stating no available embedding channels are available for the current group. Cause: No dedicated embedding model for indexing is configured. The default external service channel has no corresponding model configured, or the channel is unavailable.
Symptom: After deploying a PG database, the knowledge base index cannot be created. The file size is small, but the host has sufficient resources. Cause: chunk_size is not adjusted to fit the financial report text length, leading to memory usage exceeding virtual machine limits during segmentation. Or incremental indexing is not enabled, leading to resource exhaustion during full data import.
Symptom: The CHAT_API_KEY environment variable is configured but does not take effect, and a prompt for unavailable keys still appears. Cause: The Docker container is not rebuilt to load the new environment variable configuration. Only modifying the configuration file without restarting the service will not apply the changes.

How to Confirm Proper Configuration

Run an index import test for a single financial report file. Check the import logs for prompts indicating successful segmentation and successful vector generation. Confirm that the model configured in embedding_model is called normally.
Run a retrieval test. Enter keywords related to cosmetics financial reports. Check if the number of returned retrieval results falls within the range specified by retrieval_top_k. Confirm that the index recall logic operates correctly.
Import a new financial report file. Check if the index only adds the new data without performing a full rebuild. Confirm that the incremental index configuration is active.
Check the storage structure of the database index. Confirm that the custom field mapping rules are active, adapting to field differences across multiple companies’ financial reports.
