What the data for this category looks like
Data sources for party building material retrieval include authoritative documents from official party building platforms, internal party organization learning documents, branch activity records, and training courseware. Update cycles follow weekly or monthly schedules, with temporary document additions for major party building activities. Document types cover formal speech manuscripts, policy notices, learning Q&As, and activity minutes. Each document includes fields such as title, publishing entity, publication date, and main body text. The character count of individual documents varies widely.
Constraints for document parsing and chunking
Varied formats and structural differences in party building materials require the document parsing process to support multiple file types: PDF, Word, and scanned documents. Enable OCR processing for scanned documents to extract text. Wide variation in document character counts requires chunking logic to adapt to both short documents and long manuscripts. Avoid excessive splitting of short documents or overly large chunks for long documents. Frequently updated data sources require parsing processes to support batch task handling. Retain the unique identifier of each source file to ensure accurate distinction of chunking results after multiple file uploads. Party building-specific terminology requires chunking processes to prioritize term integrity. Prevent terms from being split across multiple chunks.
How to configure settings
This setup aligns with FastGPT v4.17.0 configuration logic.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Supports semantic integrity for long party building manuscripts, avoiding overly scattered or excessively long single chunks |
chunkSplitter | Split by paragraph and title boundaries | Preserves chapter structure of party building materials, preventing splitting from disrupting contextual coherence of specialized terminology |
customPdfParse | Enabled | Works with standard PDF-format party building materials from official sources, using the built-in parsing engine to extract accurate text |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Accommodates long document parsing time requirements, preventing timeouts for large party building report files |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports batch uploads of large training courseware or historical party literature, preventing single files from exceeding parsing limits |
chunkSettingMode | Manual configuration | Allows adjustment of chunking parameters for different file types to match the varied structures of party building materials |
Three common misconfigurations
- Phenomenon: When calling the file collection creation API, PDF parsing parameters cannot be specified. The interface returns an error indicating unsupported parameters. Cause: The
customPdfParsefield is not correctly configured in the API request's custom parameters, or the parameter format does not meet interface specifications. - Phenomenon: Frequent parsing errors occur when using doc2x to parse PDFs. Parsing tasks time out. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted for large PDF documents, or the parsing service has temporary fluctuations. - Phenomenon: After uploading multiple party building material files, chunking results cannot distinguish corresponding source files. Chunk ownership becomes mixed. Cause: File identifier retention configuration is not enabled, or the unique ID field of the source file is not bound during the chunking process.
How to verify correct configuration
- Upload a standard PDF-format party building policy document. Check that the parsed text fully retains the title, main body paragraphs, and specialized terminology.
- Initiate a batch file upload task. Confirm that the chunking result list includes the name or unique identifier of each source file.
- Adjust chunking-related configuration parameters. Parse a long manuscript and confirm that chunked content meets preset semantic integrity requirements.
- Call the file collection creation API interface. Confirm that request parameters include PDF parsing-related configuration items.
