What the data for this category looks like

Financial report data for the telecommunications equipment industry mainly comes from public disclosure platforms of the Shanghai Stock Exchange and Shenzhen Stock Exchange, as well as official investor relations pages of listed companies. Update cycles are divided into regular and real-time categories. Quarterly reports are released within 45 days after the end of the quarter. Annual reports are released within 120 days after the end of the year. Temporary announcements related to major events are updated in real time as events occur. Document structures are fixed, including modules such as main financial statement text, operating data details, and business segment analysis. Fields cover operating revenue, attributable net profit, base station shipment volume, R&D investment, and more. Units include 100 million yuan, 10,000 stations, and others.

What constraints do these characteristics place on knowledge base retrieval and recall?

Multiple data sources require the retrieval system to support cross-platform data access and unified parsing. Differentiated update cycles require a flexible incremental update mechanism to balance real-time needs for regular financial reports and temporary announcements. Fixed but multi-module document structures require retrieval results to accurately match business segments, avoiding invalid cross-segment matches. Diverse units and field types require field-level filtering rules to prevent retrieval deviations caused by unit confusion. The large size of individual documents requires a reasonable chunking and context retention strategy to ensure key information is not truncated.

Configuration Settings

Configuration ItemRecommended ValueRationale
Chunk Length800–1200 charactersTelecommunications equipment financial reports contain multiple sets of correlated financial and operating data. This length balances context integrity and chunk granularity
Recall Count10–15 entriesFinancial reports have abundant segment data, requiring retrieval results covering multiple business modules such as operators, enterprises, and consumers
Similarity Threshold0.72–0.85Financial report content is highly professional. This range filters low-relevance non-core content and retains matching results for detailed business segments
Rerank Return Count5–8 entriesLarge model context windows are limited. This value retains the most relevant core financial report data and avoids interference from redundant information
maxContext8000–12000 charactersAdapts to the multi-module combined content of telecommunications equipment financial reports, ensuring the large model can obtain complete business and financial context
Incremental Update Cycle1 day, adjustable to 6 hours during concentrated release periodsBalances regular update efficiency with real-time needs for quarterly reports and temporary announcements

Three Common Misconfiguration Issues

  • Phenomenon: After enabling the Rerank model and completing knowledge base indexing, the online recall test results do not apply the reranking logic, and the returned results are consistent with the basic recall results. Reason: The Enable Rerank switch is not enabled in the knowledge base search configuration, or the rerank model is not bound to the current application's retrieval node.
  • Phenomenon: When maxContext is set to more than 3000 characters, the context received by the large model is empty or truncated. Reason: The configured maxContext exceeds the context window limit of the currently bound large model, or the application's context limit parameter is not updated synchronously.
  • Phenomenon: After upgrading to version 4.9.0, setting the chunking repetition rate threshold or the number of recalled files does not take effect. Reason: The caching mechanism of the knowledge base configuration in version 4.9.0 does not take effect synchronously in a timely manner, and the configuration items need to be saved again.

How to Verify Proper Configuration

  • Enter the knowledge base parsing settings page, verify the configuration of Chunk Length and chunking repetition rate threshold, and check the parsing log to confirm that the chunking results follow business segment division logic.
  • Enter the application search configuration page, verify the configuration of Recall Count, Similarity Threshold, and Rerank Return Count, initiate an online recall test, and compare the ranking differences of results before and after reranking.
  • After adjusting the maxContext parameter, check whether the content returned by the large model includes complete financial report data fragments, and confirm that the context is not abnormally truncated.
  • Enter the incremental update configuration page, verify the Incremental Update Cycle setting, upload a test file, and check whether the index update status is normal.

The parameter values provided on this page are conventional recommendations used to determine the starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing the configuration.

Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
