What data looks like for this category
Documents related to glass marketing mainly come from product specifications of architectural glass manufacturers, marketing brochures, and bidding technical documents. Update cycles are irregular, aligned with new product mass production and process iterations, with no fixed schedule. Document structures are layered by glass type, such as tempered glass, insulating glass, laminated glass, etc. Each type includes fields like thickness, light transmittance, compressive strength, and size range. Most units for these fields are millimeters (mm), Pascals (Pa), and percent (%). Some documents also include installation cases and scenario description text.
What constraints do these characteristics impose on document parsing and chunking
The structured features and parameter correlations of glass marketing documents create clear constraints for parsing and chunking. Improper chunking of documents with mixed multiple glass types can lead to misalignment between parameters and their assigned categories. Splitting strongly linked parameter groups, such as thickness tied to light transmittance, will lose contextual information and reduce subsequent recall accuracy. Repeated parameter templates in long documents may be indexed multiple times, increasing the volume of irrelevant recall results. Splitting professional parameters with units into separate text blocks will separate units from their associated parameters, preventing accurate matching.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Parameter groups in glass marketing documents are mostly short text combinations. This range avoids mixing parameters from different glass types while retaining complete contextual links between related parameters |
chunk_overlap | 150–200 characters | Glass parameters have cross-chunk associations, such as thickness bound to light transmittance. Overlapping sections retain critical context and prevent parameter groups from losing their links when split |
parse_mode | "structured document parsing" | Glass marketing documents mostly include structured content such as tables and hierarchical classifications. This mode preserves field and structural information and avoids parameter misalignment |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Large glass product manuals have many pages. The default timeout duration is insufficient for full parsing. This duration supports parsing for most long documents |
recall_top_k | Top 6–8 results | Glass marketing content has many parameter dimensions. A sufficient number of recalled chunks is needed to cover complete parameter information and avoid missing critical content |
max_chunk_count | Calibrated via actual testing | Chunk counts vary widely across glass documents of different sizes. This configuration allows adjustment of the upper chunk limit based on actual document scale to prevent over-chunking |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Each scenario requires individual analysis. It is recommended to test with your own samples before finalizing settings.
Three common mistakes
- Phenomenon: An
ERR_CONTENT_TOO_LONGerror is prompted when parsing glass marketing documents, and the chunking process is interrupted. Cause: Thechunk_sizeparameter was not adjusted for the parameter density of glass documents, and a generic long chunk configuration was used, causing single-chunk content to exceed platform limits. - Phenomenon: Calling the API to retrieve chunk indexes returns empty fields in version 4.8.10. Cause: The chunk index switch was not enabled in the request parameters, or
include_chunk_indexwas not correctly set to true, so index information was not generated. - Phenomenon: Parsed chunks lose unit information, with parameters showing only numerical values and no associated units. Cause: The field extraction configuration for structured parsing was not enabled, and parameters with units were split into separate text blocks, separating units from their associated parameters.
How to confirm configuration is correct
- Upload a parameter document for a single glass type, review the parsed chunk list, and confirm each chunk contains a complete parameter group and its associated glass category name.
- Call the chunk index API for version 4.8.10, verify that the returned results include
chunk_index,content, andcategoryfields with no null values. - Upload a glass marketing manual with 10 or more pages, check that parsing completes within 300 seconds with no timeout errors.
- Input the test query "tempered glass 5mm thickness parameters", confirm that recalled chunks include related parameters such as thickness, light transmittance, and compressive strength, with no misalignment or missing content.
