What the data for this category looks like
Software development marketing content for finance, insurance, and wealth management scenarios draws data from product technical documentation, external white papers, API interface specifications, customer onboarding documents, and demo materials used for lead generation. Updates are triggered by product version iterations or marketing campaign adjustments, with update cycles ranging from several days to several months. Documents typically include structured tables, code blocks, and nested lists. Fields include version numbers, API addresses, performance parameters, and some fields have standard units: for example, request rate uses QPS, and storage capacity uses GB. Some materials contain Excel spreadsheets with merged cells or formatted PDF documents.
What constraints these characteristics impose on document parsing and chunking
Structured tables and Excel documents with merged cells cause generic parsing tools to fail at identifying correct cell relationships, requiring custom table parsing logic. Documents with multiple nested code blocks will have code sections truncated if split as plain text, which harms subsequent semantic understanding. Parameter fields with standard units must retain full parameter-unit pairs during chunking to avoid semantic breaks. Materials with inconsistent update frequencies require incremental parsing to prevent repeated processing of historical documents. Long documents must be split while preserving complete technical parameters. Do not split parameters for a single API across multiple chunks, ensuring individual chunks can independently support technical inquiries from financial customers.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Most software development marketing documents include large PDF or Excel assets; this value covers the upper limit of most conventional materials |
PARSE_SEGMENT_MAX_LENGTH | 800–1200 characters | Software development documents contain technical parameters and code snippets; this range balances semantic completeness and retrieval efficiency |
ENABLE_EXCEL_PARSE | Enabled | Software development marketing materials often include Excel-format files such as parameter tables and quotation sheets; enabling this setting correctly identifies cell content |
PARSE_CODE_BLOCK_PRESERVE | Enabled | Code blocks in documents are core technical information and must be fully retained to avoid semantic loss |
CUSTOM_SEGMENT_DELIMITER | \n\n,###,``` | Software development documents commonly use line breaks, third-level headings, and code block markers as natural segmentation points; this setting adapts to multi-format document splitting |
UPLOAD_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large Excel or PDF documents takes significant time; this value covers most parsing scenarios |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by asset format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: Parsing result is empty or cell content is misaligned after uploading an Excel document. Cause: The
ENABLE_EXCEL_PARSEconfiguration is not enabled, or the merged cell parsing logic is not adapted. - Phenomenon: After setting a custom delimiter, chunk results either merge multiple sections or split single sections. Cause: The delimiter combination is not adjusted to match natural segmentation points of software development documents, and only a single line break is used as the segmentation basis.
- Phenomenon: A
413 Request Entity Too Largeerror is triggered when uploading a PDF document larger than 3 MB. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration value is smaller than the actual file size, or theUPLOAD_FILE_TIMEOUT_SECONDSconfiguration value is insufficient, causing parsing timeout.
How to Confirm Configurations Are Set Correctly
- Upload a test document containing Excel tables and code blocks, verify that cell content in the parsing result is complete and code blocks are not truncated.
- Adjust the
PARSE_SEGMENT_MAX_LENGTHconfiguration, check if the length of chunk results matches expectations, and whether parameters for a single API are not split across multiple chunks. - Upload a test asset of the maximum allowed size, confirm that the upload and parsing process does not trigger timeout or file size limit errors.
- Import a manually segmented document, verify that the custom delimiter takes effect and chunks follow the preset segmentation logic.
