What this category of data looks like
Data sources include internal party committee-issued study manuals, three meetings and one lesson records, integrity education materials, and party building guidance documents distributed by superior state-owned assets supervision and administration institutions. The update cadence follows monthly refreshes for internal study materials and quarterly updates for superior policy documents. Most documents use structured formats, with fields including title, publishing entity, publishing date, and content classification. Content focuses on theoretical explanations and work specifications. The length of individual documents varies widely. Some include text content translated from attachments.
What constraints these characteristics impose on knowledge base retrieval and recall
Data sources are scattered across internal OA, shared drives and other channels. Retrieval configuration must support multi-data source associated recall. Update cycles are inconsistent. Incremental sync trigger rules matching the business cycle must be set to avoid data lag or duplicate indexing. Documents have clear party building classification tags. Retrieval must support filtering results by tags to ensure recalled content aligns with study topics. Some documents are lengthy. A reasonable chunking strategy is needed to avoid semantic breaks and control single chunk length to fit model context limits. Some documents have internal permission markers. Recall scope must be combined with permission controls to prevent sensitive content leaks.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.72–0.85 | Party building content has high semantic similarity. This range filters low-relevance results while retaining sufficient recall volume |
limit | top 8 entries | Party building learning Q&A needs to cover multi-dimensional study materials. Around 8 entries can meet multi-scenario reference needs |
searchMode | hybrid vector retrieval + keyword retrieval | Party building documents have both clear keywords such as "three meetings and one lesson" and semantically related content. Hybrid mode enables more comprehensive recall |
usingReRank | enabled | There are many entries with similar semantics in party building content. Reranking improves the accuracy of result relevance ranking |
datasetSearchUsingExtensionQuery | enabled | Party building questions often use industry-specific expressions. Extended queries can cover more relevant documents |
collectionIds | bind dedicated party building dataset ID | Isolate data from other categories to ensure recalled results only come from the state-owned capital investment company's party building knowledge base |
Three common mistakes
- Phenomenon: Empty results or no matching content returned when calling the retrieval API. Cause: The
collectionIdsparameter is not correctly configured to bind the corresponding party building dataset. The retrieval scope does not cover the target data. - Phenomenon: Crash or error reports appear on the chat page or knowledge base page. Cause: The
limitparameter value is not restricted. Too many documents recalled in a single request cause context overflow, triggering FastGPT v4.17.0 resource restriction rules. - Phenomenon: Retrieval results mix non-party building state-owned capital operation content. Cause: Classification filtering for
searchModeis not enabled, or the dataset scope is not limited viacollectionIds. This results in recalled documents from other categories.
How to confirm the configuration is correct
- Check the FastGPT retrieval configuration panel to confirm that
collectionIdshas been bound to the state-owned capital investment company's dedicated party building dataset ID. - Initiate a test query, enter a party building-related question, and verify that the titles and content of the returned results all come from party building documents, with no cross-category content.
- Adjust the
similarityparameter range, observe changes in the relevance of recalled results, and confirm that the value meets the business requirements for accuracy. - Trigger an incremental sync task, wait for the preset sync cycle, and confirm that newly uploaded party building documents can be retrieved normally.
