|
||
Load text documents into processing pipeline for indexing and embedding.
|
||
|
||
## Text Load Overview
|
||
|
||
Fire-and-forget document loading:
|
||
- **Input**: Text content (raw UTF-8 or base64 encoded)
|
||
- **Process**: Chunk, embed, store
|
||
- **Output**: None (202 Accepted)
|
||
|
||
Asynchronous processing - document queued for background processing.
|
||
|
||
## Processing Pipeline
|
||
|
||
Text documents go through:
|
||
1. **Chunking**: Split into overlapping chunks
|
||
2. **Embedding**: Generate vectors for each chunk
|
||
3. **Storage**: Store chunks + embeddings
|
||
4. **Indexing**: Make searchable via document-embeddings query
|
||
|
||
Pipeline runs asynchronously after request returns.
|
||
|
||
## Text Format
|
||
|
||
Text may be sent as raw UTF-8 text:
|
||
```
|
||
{
|
||
"text": "Cancer survival: 2.74× higher hazard ratio"
|
||
}
|
||
```
|
||
|
||
Older clients may still send base64 encoded text:
|
||
```
|
||
text_content = "This is the document..."
|
||
encoded = base64.b64encode(text_content.encode('utf-8'))
|
||
```
|
||
|
||
Default charset is UTF-8, specify `charset` if different.
|
||
|
||
## Metadata
|
||
|
||
Optional RDF triples describing document:
|
||
- Title, author, date
|
||
- Source URL
|
||
- Custom properties
|
||
- Used for organization and retrieval
|
||
|
||
## Use Cases
|
||
|
||
- **Document ingestion**: Add documents to knowledge base
|
||
- **Bulk loading**: Process multiple documents
|
||
- **Content updates**: Replace existing documents
|
||
- **Library integration**: Load from document library
|
||
|
||
## No Response Data
|
||
|
||
Returns 202 Accepted immediately:
|
||
- Document queued for processing
|
||
- No synchronous result
|
||
- No processing status
|
||
- Check document-embeddings query later to verify indexed
