What the data for this category looks like
Water treatment marketing content for finance, insurance and wealth management scenarios uses data sources including process manuals from water utility operators, daily water quality monitoring reports, project completion documents, compliant emission standard documents and marketing solution materials. Update rhythms vary significantly: process standard documents have long update cycles, water quality monitoring data is updated daily, and marketing materials are adjusted dynamically alongside projects. Most documents use a structure of structured parameters paired with text explanations, with fields including treatment capacity (unit: m³/d), influent water quality indicators (such as COD, NH3-N), equipment models, emission standard numbers, project cycles and more. Some documents are long-text process explanations or case reviews.
What constraints do these characteristics impose on retrieval and recall
The multi-structured parameters, dynamically updated monitoring data and long-text process documents of the water treatment category impose multiple constraints on the retrieval and recall process. Structured water quality parameters, treatment capacity and other fields require matching units and value ranges, and cannot rely solely on semantic association. Invalid recalls with parameter mismatches will occur otherwise. Daily updated water quality monitoring data requires an incremental indexing mechanism to avoid excessive resource usage from full indexing. Long-text process explanation documents need reasonable segment thresholds to avoid cross-paragraph semantic breaks that reduce recall relevance. Dynamic adjustments to marketing materials need to support fast triggering of partial index updates to maintain content timeliness.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 800–1200 characters | Most water treatment documents contain long-text process explanations and structured parameters. This range preserves the association between parameters and their context, avoiding segment breaks |
recall count | Top 8–12 results | Water treatment marketing content covers multiple types of information including process parameters, project cases and compliance standards. A moderate recall count ensures comprehensive information coverage |
similarity threshold | 0.72–0.80 | Semantic precision requirements are high for water treatment parameter content. A threshold that is too low will introduce irrelevant documents, while a threshold that is too high may miss matching compliance standards |
incremental indexing trigger mechanism | Triggered by file modification time | Water quality monitoring data is updated daily. Triggering based on modification time only updates changed content, reducing indexing time |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing some long-text process manuals takes a long time. This duration ensures complete parsing without interruption |
maxContext | 4000–5000 characters | Multiple matching segments need to be spliced after retrieval. This range covers complete parameters and explanations for a single project, avoiding insufficient context |
The parameter values provided on this page are common starting points for determining configurations. Actual values are affected by material format, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- Phenomenon: Search results contain content with mismatched parameter units, such as mixing documents with influent COD measured in mg/L with results using other units. Cause: No unified unit parsing rule is configured, and only text semantic matching is used, leading to unit ambiguity.
- Phenomenon: Duplicate project case documents remain after index merging. Cause: The document deduplication configuration item is not enabled, or the deduplication threshold is set too high, causing similar documents to not be merged.
- Phenomenon: Water treatment compliance standard documents on external websites cannot be recalled normally, returning a 403 status code. Cause: No whitelist or request headers for external website crawling are configured, causing crawling requests to be blocked.
How to confirm the configuration is properly set
- Upload a single test document with clear water quality parameters, search for the core parameters in the document, and verify that the units and parameter ranges of the recall results match.
- Upload two project case documents with highly similar content, trigger index merging, and check that only one deduplicated document remains in the knowledge base.
- Modify the content of a daily water quality monitoring report, wait for index updates to complete, search for the updated document content, and confirm that the recall results include the latest modified information.
- Configure external website crawling rules, attempt to search for water treatment compliance standard content on the website, and confirm that relevant documents can be recalled normally.
