**Fix SnowflakeLoader's Behavior of Returning Empty Documents**
**Description:**
This PR addresses the issue where the SnowflakeLoader was consistently
returning empty documents. After investigation, it was found that the
query method within the SnowflakeLoader was not properly fetching and
processing the data.
**Changes:**
1. Modified the query method in SnowflakeLoader to handle data fetch and
processing more accurately.
2. Enhanced error handling within the SnowflakeLoader to catch and log
potential issues that may arise during data loading.
**Impact:**
This fix will ensure the SnowflakeLoader reliably returns the expected
documents instead of empty ones, improving the efficiency and
reliability of data processing tasks in the LangChain project.

**Tests:**
All unit and integration tests have been run and passed successfully.
Additional tests were added to validate the new behavior of the
SnowflakeLoader.

- [x] Code changes are covered by tests
- [x] Code passes `make format` and `make lint`
- [x] This PR does not introduce any breaking changes
Please review and let me know if any changes are required.
"One Retriever to merge them all, One Retriever to expose them, One
Retriever to bring them all and in and process them with Document
formatters."
Hi @dev2049! Here bothering people again!
I'm using this simple idea to deal with merging the output of several
retrievers into one.
I'm aware of DocumentCompressorPipeline and
ContextualCompressionRetriever but I don't think they allow us to do
something like this. Also I was getting in trouble to get the pipeline
working too. Please correct me if i'm wrong.
This allow to do some sort of "retrieval" preprocessing and then using
the retrieval with the curated results anywhere you could use a
retriever.
My use case is to generate diff indexes with diff embeddings and sources
for a more colorful results then filtering them with one or many
document formatters.
I saw some people looking for something like this, here:
https://github.com/hwchase17/langchain/issues/3991
and something similar here:
https://github.com/hwchase17/langchain/issues/5555
This is just a proposal I know I'm missing tests , etc. If you think
this is a worth it idea I can work on tests and anything you want to
change.
Let me know!

# Expose full params in Qdrant
There were many questions regarding supporting some additional
parameters in Qdrant integration. Qdrant supports many vector search
optimizations that were impossible to use directly in Qdrant before.
That includes:
1. Possibility to manipulate collection params while using
`Qdrant.from_texts`. The PR allows setting things such as quantization,
HNWS config, optimizers config, etc. That makes it consistent with raw
`QdrantClient`.
2. Extended options while searching. It includes HNSW options, exact
search, score threshold filtering, and read consistency in distributed
mode.
After merging that PR, #4858 might also be closed.

This PR adds the possibility of specifying the endpoint URL to AWS in
the DynamoDBChatMessageHistory, so that it is possible to target not
only the AWS cloud services, but also a local installation.
Specifying the endpoint URL, which is normally not done when addressing
the cloud services, is very helpful when targeting a local instance
(like [Localstack](https://localstack.cloud/)) when running local tests.

#### Add start index to metadata in TextSplitter
- Modified method `create_documents` to track start position of each
chunk
- The `start_index` is included in the metadata if the `add_start_index`
parameter in the class constructor is set to `True`
This enables referencing back to the original document, particularly
useful when a specific chunk is retrieved.

I ran into an issue where load_qa_chain was not passing the callbacks
down to the child LLM chains, and so made sure that callbacks are
propagated. There are probably more improvements to do here but this
seemed like a good place to stop.
Note that I saw a lot of references to callbacks_manager, which seems to
be deprecated. I left that code alone for now.

Also removed an extra code block at the end of the file.
Along the way, the current outputs seem to have changed in a few places
so left that for posterity, and updated the number of runs which seems
harmless, though I can clean that up if preferred.
Implementation of similarity_search_with_relevance_scores for quadrant

As implemented the method is also compatible with other capacities such
as filtering.

### Summary
Adds an `UnstructuredCSVLoader` for loading CSVs. One advantage of using
`UnstructuredCSVLoader` relative to the standard `CSVLoader` is that if
you use `UnstructuredCSVLoader` in `"elements"` mode, an HTML
representation of the table will be available in the metadata.

Hi! I just added an example of how to use a custom scraping function
with the sitemap loader. I recently used this feature and had to dig in
the source code to find it. I thought it might be useful to other devs
to have an example in the Jupyter Notebook directly.
I only added the example to the documentation page.
@eyurtsev I was not able to run the lint. Please let me know if I have
to do anything else.
I know this is a very small contribution, but I hope it will be
valuable. My Twitter handle is @web3Dav3.
