What This Category of Data Looks Like
Data sources for this category include monitoring systems, ticket systems, contract documents, and customer communication records. Update frequency is monthly or quarterly. Daily documents include SLA clauses, monthly service reports, availability statistics tables, and customer review minutes. Fields include service time indicators, customer contract identifiers, event occurrence times, compliance check items, and more. There is no fixed uniform single-document length. Data is grouped and stored according to business archive cycles.
What Constraints These Characteristics Impose on Knowledge Base Retrieval and Recall
This category of data is scattered across multiple systems. It includes structured contract clauses and ticket records, plus unstructured review minutes. Retrieval logic must support multiple formats. Update frequency is monthly or quarterly. High-frequency incremental synchronization is not required. Indexes must be updated according to archive cycles to maintain data timeliness. Documents contain compliance check-related fields. Non-authorized content must be filtered during retrieval to avoid compliance risks. SLA-related indicators are the core retrieval targets. Retrieval ranking must combine field relevance and keyword matching accuracy. Irrelevant content must be prevented from interfering with SLA indicator calculation and report caliber alignment.
How to Configure Settings
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Matches keyword accuracy for SLA clauses and ticket records, balances recall completeness and relevance |
limit | Top 10 entries | Controls the number of documents retrieved per request, avoids excessive content slowing response, meets the small-batch precise retrieval needs of SLA reports |
searchMode | hybrid | Combines keyword and semantic retrieval, adapts to mixed structured and unstructured SLA category data |
usingReRank | Enabled | Re-ranks retrieval results, prioritizes passages related to SLA core indicators, improves report caliber alignment efficiency |
datasetSearchUsingExtensionQuery | Enabled | Automatically optimizes user-input SLA-related questions, supplements implicit retrieval terms such as contract numbers and time thresholds |
collectionIds | Configured by business archive groups | Only retrieves corresponding monthly/quarterly archived SLA document sets, narrows retrieval scope and improves response speed |
Three Common Configuration Errors
- API calls return no knowledge base matching results. The cause is failure to bind the correct
collectionIdsparameter in the API request, or failure to enable knowledge base retrieval permissions. - Retrieval response time exceeds 30 seconds. The cause is enabling both
usingReRankanddatasetSearchUsingExtensionQuery, with an excessively high retrievallimitvalue, exceeding single-request processing thresholds. - Retrieval results do not link to specified file names. The cause is failure to set
searchModeto a multi-source document compatible mode, or failure to enable file name association indexing in retrieval parameters.
How to Confirm Correct Configuration
- Check that API request parameters include the configured
collectionIds, and that they match the target SLA document sets. - Review retrieval logs to confirm that the switch states of
usingReRankanddatasetSearchUsingExtensionQuerymatch the configured settings. - Initiate a test retrieval, input a question containing SLA time indicator keywords, verify that the relevance and quantity of returned results meet the configured
limitandsimilarityrequirements. - Verify response time, confirm that the duration falls within an acceptable business range for the configured parameter combination.
The values listed are common starting points, and should be evaluated against samples specific to the target use case.
