### Environment:
Using nightly version
Commit version:
[[6051abb](6051abb4a3)]
### Bug Description:
The retrieval function in rag/nlp/search.py returns the original total
chunks number
even after chunks are filtered by similarity_threshold. This creates
inconsistency
between the actual returned chunks and the reported total.
### Changes Made:
Added code to count how many search results actually meet or exceed the
configured similarity threshold
Positioned the calculation after the doc_ids conditional logic to ensure
special cases are handled correctly
Updated the ranks["total"] value to store this filtered count instead of
using the raw search result count
Using NumPy leverages optimized C-level batch operations to optimize
speed
### What problem does this PR solve?
fix#6085
RagTokenizer's dfs_() function falls into infinite recursion when
processing text with repetitive Chinese characters (e.g.,
"一一一一一十一十一十一..." or "一一一一一一十十十十十十十二十二十二..."), causing memory leaks.
### Type of change
Implemented three optimizations to the dfs_() function:
1.Added memoization with _memo dictionary to cache computed results
2.Added recursion depth limiting with _depth parameter (max 10 levels)
3.Implemented special handling for repetitive character sequences

### What problem does this PR solve?
This PR fixes an AttributeError in the all_tags method of the Dealer
class. Previously, the method incorrectly called
self.docStoreConn.indexExist instead of self.dataStore.indexExist. Since
self.docStoreConn was never set (and self.dataStore is already
initialized in init), this resulted in an error when attempting to check
if the index exists. This change ensures that the proper connector is
used for the index existence check, thereby resolving the issue._

Use `json.loads()` instead.
### What problem does this PR solve?
Using `eval()` can lead to code injections. I think this loads a JSON
field, right? If yes, why is this done via `eval()` and not
`json.loads()`?
