What data for this category looks like
Small home appliance investment research data primarily originates from official product manuals, e-commerce platform parameter pages, industry compliance test reports, and supply chain collaboration documents. Update frequency follows new product launch cycles, with higher rates during concentrated new product release periods. Document structures include structured parameter tables, short usage tips, compliance certification labels, and after-sales instructions. Common fields cover rated power, product dimensions, net weight, and similar items, with fixed accompanying units such as watts (W), millimeters (mm), kilograms (kg). Some documents contain cross-page parameter correlations.
What constraints do these characteristics impose on document parsing and chunking?
Structured parameter tables account for a large portion of small home appliance documents, and most parameter rows are short entries. Chunking processes must avoid splitting table structures, which would break parameter sets. Frequently updated new product documents require parsing workflows that support batch uploads, requiring a balance between parsing speed and accuracy. Some documents have cross-page parameter correlations, so chunking must preserve contextual connections to avoid dispersing parameter information. Documents exported from e-commerce platforms have inconsistent formats, including both editable text and scanned copies, so parsing modes must support multiple input types.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
enable_table_parse | Enabled | Small home appliance documents contain large numbers of structured parameter tables. Enabling this setting preserves complete table structures and prevents incorrect splitting of parameter rows |
chunk_size | 800–1000 characters | Small home appliance documents have fragmented parameters and short paragraphs. This range balances contextual association and recall precision |
chunk_overlap | 100–150 characters | Prevents contextual breaks across parameter rows, and adapts to the short paragraph and cross-page parameter correlation characteristics of small home appliance documents |
custom_delimiter | Line breaks, table separators | Adapts to Excel/CSV format supply chain documents for small home appliances, splitting by row to avoid merging multiple lines of content into a single chunk |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to parsing of small home appliance product manuals over 10MB, preventing task failure caused by insufficient default timeout duration |
UPLOAD_FILE_MAX_SIZE | 20 MB | Covers the standard file sizes of most small home appliance product manuals and industry reports |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific scenarios require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Scenario: When uploading a Word format product manual over 10MB, parsing progress stays unchanged for an extended period before triggering a timeout error. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. The default timeout setting of FastGPT v4.8.12-alpha open source version is insufficient for processing long documents such as small home appliance manuals. - Scenario: Small home appliance parameter tables imported from Excel are automatically split, with multiple sets of parameters for different models merged into a single chunk. Cause:
custom_delimiterwas not configured to use line breaks. The default chunking rule does not split structured table data by row. - Scenario: Queries containing specific rated power parameters fail to retrieve the corresponding parameter chunks from documents. Cause:
enable_table_parsewas not enabled. Table content is recognized as plain text and incorrectly split, leading to failure of accurate parameter information matching.
How to confirm correct configuration
- Upload a single small home appliance instruction manual PDF, examine the parsed chunk list to confirm parameter tables are displayed as complete chunks.
- Upload a batch of Excel parameter files, verify each chunk’s content corresponds to a single row of data.
- Upload a large document over 10MB, monitor parsing logs to confirm no timeout errors are triggered.
- Enter queries containing specific small home appliance parameters, confirm corresponding chunks are retrieved normally.
