### Type of change
- [x] New Feature (non-breaking change which adds functionality)
### Bug
`RAGFlowHtmlParser.chunk_block()` splits an oversized block by slicing
the **tokenized** string and storing the joined tokens:
```python
tks_str = rag_tokenizer.tokenize(block)
...
tokens = tks_str.split(" ")
while start < len(tokens):
chunks.append(" ".join(tokens[start:start + chunk_token_num])) # tokenized form, not source
```
On the default (Elasticsearch) backend `rag_tokenizer.tokenize`
transforms text: it lowercases/stems Latin words and inserts spaces
between CJK characters. So any text block longer than `chunk_token_num`
is stored as garbled, lowercased, space-segmented text instead of the
source content. The small-block branch correctly stores the original
`block`, so only oversized blocks are corrupted. Affects HTML and EPUB
ingestion (both go through `chunk_block`), degrading retrieved chunks
and the answers generated from them.
### Real tokenizer behavior (infinity-sdk 0.7.0, ES backend)
```
tokenize("Hello World FOO Bar Baz Qux Jumps") -> "hello world foo bar baz qux jump" # lowercased + stemmed
tokenize("你好世界这是一个测试") -> "你好世界 这 是 一个 测试" # spaces inserted
```
### Fix
Split the **original** text: break it into atoms (whitespace-delimited
runs for space-separated scripts, per-character for spaceless scripts
such as Chinese) and pack them into pieces of at most `chunk_token_num`
tokens. This preserves the source characters and still splits scripts
that have no whitespace — a plain whitespace split would leave CJK as
one un-splittable chunk.
### Proof (real tokenizer, before/after)
Running the old vs new split against the real `infinity.rag_tokenizer`:
```
ENGLISH "Hello World FOO Bar Baz Qux Lazy Dogs" (chunk_token_num=4)
OLD: ['hello world foo bar', 'baz qux jump over', 'lazi dog'] # lowercased + stemmed
NEW: ['Hello World FOO Bar ', 'Baz Qux Jumps Over ', 'Lazy Dogs'] # preserved; each <= 4 tokens
NEW preserves text exactly: True
CHINESE "你好世界这是一个测试用例需要被切分成多个块" (chunk_token_num=3)
OLD: ['你好世界 这 是', '一个 测试用例 需要', ...] # spurious spaces
NEW: ['你好世', '界这是', '一个测', ...] # preserved; each <= 3 tokens
NEW preserves text exactly: True
```
### Tests
Added `test/unit_test/deepdoc/parser/test_html_parser.py` (English +
Chinese oversized blocks, plus small-block merge). Before the fix the
two oversized tests fail (English shows lowercasing, Chinese shows
inserted spaces); after the fix all pass. `ruff check` clean.
### What problem does this PR solve?
`DeepLParam.check()` validated `self.top_n`, but DeepL has no such
parameter (it is not defined on the param class or its base), so
`check()` always raised `AttributeError` and a DeepL component could
never pass validation. Removed the bogus `top_n` check.
Also fixed the `_run` except branch, which computed
`be_output("**Error**...")` but never returned it, silently dropping the
error message.
Closes#16329
### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)
- [x] Add test cases
### Testing
Added `test/unit_test/agent/component/test_deepl.py` covering
`DeepLParam.check()` with valid defaults and rejection of invalid
source/target languages.
### What problem does this PR solve?
Fixes the PubMed tool always emitting `Authors: Unknown Authors`. The
`safe_find` closure in `_format_pubmed_content` was hardcoded to search
from the article root, so the per-author `LastName`/`ForeName` lookups
never matched.
`safe_find` now accepts an optional `base` node (defaults to `child`,
preserving the existing field lookups), and the author loop passes the
current `<Author>` element.
Closes#16328
### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)
- [x] Add test cases
### Testing
Added `test/testcases/test_web_api/test_canvas_app/test_pubmed_unit.py`
covering per-author parsing, intact title/journal/DOI fields, and the
no-authors fallback.
Before: `Authors: Unknown Authors`
After: `Authors: Furqan Khan, Jane Smith`
## Summary
Add the Go implementation of `POST
/api/v1/datasets/{dataset_id}/documents/{document_id}/chunks`.
This wires the full create-chunk path in Go:
- router and handler registration
- request/response structs
- chunk creation service logic
- embedding generation
- chunk insert into doc engine
- chunk/token counter increment
- `tag_feas` validation
- `image_base64` decoding and chunk image storage/merge
- unit tests for handler and service
## Testing
Unit tests:
- `/usr/local/go/bin/go test ./internal/handler`
- `/usr/local/go/bin/go test ./internal/service/chunk`
- `/usr/local/go/bin/go test ./internal/service`
- `/usr/local/go/bin/go test ./...`
All passed locally.
Manual curl checks:
- basic text chunk: Go passed
- chunk with `important_keywords` / `questions` / `tag_kwd` /
`tag_feas`: Go passed
- blank content validation: Go matched expected `code=102`
- invalid `image_base64` validation: Go matched expected `code=102`
- image upload and repeated image upload / merge path: Go passed twice

## Summary
Migrated the dataset document upload API (`POST
/api/v1/datasets/:dataset_id/documents`) from Python to the Go backend.
It supports local file uploads (`type=local`), web page ingestion
(`type=web`), and empty document creation (`type=empty`).
## Changes
- **Router**: Registered `POST /api/v1/datasets/:dataset_id/documents`
route.
- **Handler**: Implemented `UploadDocuments` handler and its routing
functions (`uploadLocalDocuments`, `uploadWebDocument`,
`uploadEmptyDocument`).
- **Service**: Implemented `UploadLocalDocuments`, `UploadWebDocument`,
and `UploadEmptyDocument` in `DocumentService`.
- **Refactoring**: Moved permission checking logic to a shared helper
for reuse in file and document services.
- **Tests**: Added comprehensive unit tests for the new handler and
service upload paths.
## Verification
Ran and passed the test suite for service and handler packages:
- `go test ./internal/service`
- `go test ./internal/handler`
### What problem does this PR solve?
- added the new dataset search route and handler
- reused the existing shared SearchDatasets service by adapting
single-dataset requests into dataset_ids=[dataset_id]
- aligned handler error responses with Python behavior for argument/data
errors
- aligned key service error messages such as invalid search_id and mixed
embedding models
- added focused handler and service tests for request mapping and error
behavior
### Tests:
`/usr/local/go/bin/go test ./internal/service -run
'TestSearchDatasetRequestToSearchDatasetsRequest|TestDatasetServiceSearchDatasets'`
`/usr/local/go/bin/go test ./internal/handler -run
'TestDatasetsHandlerSearchDataset'`
## Problem
The Wikipedia tool silently swallows all exceptions with `except
Exception: pass`, making it impossible to debug failures when fetching
Wikipedia pages.
## Fix
Replace the bare `except Exception: pass` with specific exception
handling:
- `DisambiguationError`: log available options
- `PageError`: log page not found
- `Exception`: log unexpected errors with full traceback
