I have changed the name of the argument from `where` to `filter` which
is expected by `similarity_search_with_score`.
Fixes#1838

Hi, first and foremost, I would like to express my gratitude for your
outstanding work; it's truly remarkable!
https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/qdrant.py#L134
It appears that there might be a minor issue with the `limit` parameter
being passed incorrectly in the `Qdrant.maximal_marginal_relevance`
function. This seems to be a typographical error.

I noticed that the "getting started" guide section on agents included an
example test where the agent was getting the question wrong 😅
I guess Olivia Wilde's dating life is too tough to keep track of for
this simple agent example. Let's change it to something a little easier,
so users who are running their agent for the first time are less likely
to be confused by a result that doesn't match that which is on the docs.
Added support for document loaders for Azure Blob Storage using a
connection string. Fixes#1805

Ran into a broken build if bs4 wasn't installed in the project.
Minor tweak to follow the other doc loaders optional package-loading
conventions.
Also updated html docs to include reference to this new html loader.
side note: Should there be 2 different html-to-text document loaders?
This new one only handles local files, while the existing unstructured
html loader handles HTML from local and remote. So it seems like the
improvement was adding the title to the metadata, which is useful but
could also be added to `html.py`
Fixed a typo in the argument of the query method within the
VectorStoreIndexWrapper class. Specifically, the argument `retriver` has
been changed to `retriever`. With this correction, the correct argument
name is used, and potential bugs are avoided.
# Description
Add `drop_index` for redis
RediSearch: [RediSearch quick
start](https://redis.io/docs/stack/search/quick_start/)
# How to use
```
from langchain.vectorstores.redis import Redis
Redis.drop_index(index_name="doc",delete_documents=False)
```
Technically a duplicate fix to #1619 but with unit tests and a small
documentation update
- Propagate `filter` arg in Chroma `similarity_search` to delegated call
to `similarity_search_with_score`
- Add `filter` arg to `similarity_search_by_vector`
- Clarify doc strings on FakeEmbeddings
In https://github.com/hwchase17/langchain/issues/1716 , it was
identified that there were two .py files performing similar tasks. As a
resolution, one of the files has been removed, as its purpose had
already been fulfilled by the other file. Additionally, the init has
been updated accordingly.
Furthermore, the how_to_guides.rst file has been updated to include
links to documentation that was previously missing. This was deemed
necessary as the existing list on
https://langchain.readthedocs.io/en/latest/modules/document_loaders/how_to_guides.html
was incomplete, causing confusion for users who rely on the full list of
documentation on the left sidebar of the website.
In the langchain.vectorstores.opensearch_vector_search.py, in the
add_texts function, around line 247, we have the following code
```python
embeddings = [
self.embedding_function.embed_documents(list(text))[0] for text in texts
]
```
the goal of the `list(text)` part I believe is to pass a list to the
embed_documents list instead of a a str. However, `list(text)` is a
subtle bug
`list(text)` would convert the string text into an array, where each
element of the array is a character of the string

The correct way should be to change the code to
```python
embeddings = [
self.embedding_function.embed_documents([text])[0] for text in texts
]
```
Which wraps the string inside a list.
The `CollectionStore` for `PGVector` has a `cmetadata` field but it's
never used. This PR add the ability to save metadata information to the
collection.
