What This Category’s Data Looks Like
Ordnance and equipment financial report data sources include public periodic reports of listed companies, public documents from military industry associations, and official operational disclosure documents of group companies. Update cadence falls into three categories: annual reports, semi-annual reports, and temporary announcements. Annual reports are disclosed once per year, semi-annual reports are disclosed every six months, and temporary announcements are released immediately for major business events. Document structures include multi-chapter structured text, covering financial statement schedules, business segment details, summaries of major contracts, and more. Some documents include tabular data related to orders, production capacity, and research and development. Fields include equipment model names, transaction amounts, delivery quantities, research and development expenditures, and more. Units include RMB yuan, units, sets, and others.
Constraints on Vector Models and Indexing
The mixed format of ordnance and equipment financial reports requires vector models to support both structured field encoding and unstructured natural language text encoding, to avoid encoding bias for professional terms. The combined regular and irregular update cadence requires indexes to support flexible switching between incremental updates and full reconstruction, to avoid excessive resource usage from full reconstruction. The wide variation in document length requires a segmentation strategy that adapts to text fragments of different lengths, to prevent truncation of critical equipment model and order data. The dense use of professional terms requires vector models to adapt to military industry-specific semantics, to improve the relevance of recall results.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
CHUNK_SIZE | 800–1200 characters | Adapts to long paragraph business descriptions and short tabular text in ordnance and equipment financial reports, to avoid truncation of critical information |
CHUNK_OVERLAP | 150–200 characters | Retains contextual association between segments, to avoid losing front and back logical connections in split financial report paragraphs |
INDEX_BATCH_SIZE | 50–100 items per batch | Adapts to the number of documents for batch import of ordnance and equipment financial reports, balances index construction speed and server load |
SIMILARITY_THRESHOLD | 0.72–0.85 | Adapts to semantic similarity matching for military professional terms, filters low-relevance recall results |
RECALL_TOP_K | Top 8–12 items | Covers multi-dimensional retrieval needs for segmented equipment models in ordnance and equipment financial reports, to avoid missing critical business data |
INDEX_INCREMENTAL_ENABLE | Enabled | Adapts to regularly updated financial report data, supports incremental indexing without full reconstruction, shortens update duration |
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, and it is recommended to test on your own samples before finalizing.
Three Common Errors
- Index reconstruction tasks that run for more than 12 hours, with the interface showing an "Index Building" status beyond a reasonable duration, and the log returns an
ETIMEDOUTerror. Cause: TheINDEX_BATCH_SIZEparameter is not configured, and the default single-item import mode is used to process batch ordnance and equipment financial report documents, without sharding optimization. - Batch index addition requests return a
400 Bad Requesterror. Cause: TheDOCUMENT_IDSbatch parameter list is not correctly passed, and the document identifiers for batch import are not encapsulated according to interface requirements. - Retrieval results only contain fragments from a single document, and cannot recall associated equipment model data across documents. Cause: A separate index is created for each ordnance and equipment financial report, and a unified collection index is not used, preventing cross-document semantic association from being retrieved.
How to Confirm Proper Configuration
- View index construction logs to confirm that the effective value of the
INDEX_BATCH_SIZEparameter matches the configured value, with no sharding failure records. - Submit a test retrieval request for military professional terms, verify that the number of recall items matches the
RECALL_TOP_Ksetting, with no abnormal filtering. - Upload a single ordnance and equipment financial report document, check that incremental indexing is triggered, no full reconstruction is performed, and confirm that update duration meets expectations.
- Compare retrieval results under different segmentation strategies, confirm that the configurations for
CHUNK_SIZEandCHUNK_OVERLAPdo not lose critical business context.
