## Description
Added Office365 tool modules to `__init__.py` files
## Issue
As described in Issue
https://github.com/hwchase17/langchain/issues/6936, the Office365
toolkit can't be loaded easily because it is not included in the
`__init__.py` files.

Description:
The OpenAI "embeddings" API intermittently falls into a failure state
where an embedding is returned as [ Nan ], rather than the expected 1536
floats. This patch checks for that state (specifically, for an embedding
of length 1) and if it occurs, throws an ApiError, which will cause the
chunk to be retried.
Issue:
I have been unable to find an official langchain issue for this problem,
but it is discussed (by another user) at
https://stackoverflow.com/questions/76469415/getting-embeddings-of-length-1-from-langchain-openaiembeddings
Maintainer: @dev2049
Testing:
Since this is an intermittent OpenAI issue, I have not provided a unit
or integration test. The provided code has, though, been run
successfully over several million tokens.

When using AsyncIteratorCallbackHandler with OpenAIFunctionsAgent, if
the LLM response function_call instead of direct answer, the
AsyncIteratorCallbackHandler.on_llm_new_token would be called with empty
string.
see also: langchain.chat_models.openai.ChatOpenAI._generate
An alternative solution is to modify the
langchain.chat_models.openai.ChatOpenAI._generate and do not call the
run_manager.on_llm_new_token when the token is empty string.
I am not sure which solution is better.

uses SPARQL, but specifically for wikibase querying
* [Cypher qa](https://github.com/hwchase17/langchain/pull/5078) - graph
DB question answering for Neo4J via Cypher
* [PR 6050](https://github.com/hwchase17/langchain/pull/6050) - tries
something similar, but does not cover UPDATE queries and supports only
RDF
* Discussions on [w3c mailing list](mailto:semantic-web@w3.org) related
to the combination of LLMs (specifically ChatGPT) and knowledge graphs

- Description: rename the invalid function name of GoogleSerperResults
Tool for OpenAIFunctionCall
- Tag maintainer: @hinthornw
When I use the GoogleSerperResults in OpenAIFunctionCall agent, the
following error occurs:
```shell
openai.error.InvalidRequestError: 'Google Serrper Results JSON' does not match '^[a-zA-Z0-9_-]{1,64}$' - 'functions.0.name'
```
So I rename the GoogleSerperResults's property "name" from "Google
Serrper Results JSON" to "google_serrper_results_json" just like
GoogleSerperRun's name: "google_serper", and it works.
I guess this should be reasonable.

Hi @rlancemartin, @eyurtsev!
- Description: Adding HNSW extension support for Postgres. Similar to
pgvector vectorstore, with 3 differences
1. it uses HNSW extension for exact and ANN searches,
2. Vectors are of type array of real
3. Only supports L2
- Dependencies: [HNSW](https://github.com/knizhnik/hnsw) extension for
Postgres
- Example:
```python
db = HNSWVectoreStore.from_documents(
embedding=embeddings,
documents=docs,
collection_name=collection_name,
connection_string=connection_string
)
query = "What did the president say about Ketanji Brown Jackson"
docs_with_score: List[Tuple[Document, float]] =
db.similarity_search_with_score(query)
```
The example notebook is in the PR too.
- correct `endpoint_name` to `api_url`
- add `headers`

[Apache HugeGraph](https://github.com/apache/incubator-hugegraph) is a
convenient, efficient, and adaptable graph database, compatible with the
Apache TinkerPop3 framework and the Gremlin query language.
In this PR, the HugeGraph and HugeGraphQAChain provide the same
functionality as the existing integration with Neo4j and enables query
generation and question answering over HugeGraph database. The
difference is that the graph query language supported by HugeGraph is
not cypher but another very popular graph query language
[Gremlin](https://tinkerpop.apache.org/gremlin.html).
A notebook example and a simple test case have also been added.

This PR introduces a new Mendable UI tailored to a better search
experience.
We're more closely integrating our traditional search with our AI
generation.
With this change, you won't have to tab back and forth between the
mendable bot and the keyword search. Both types of search are handled in
the same bar. This should make the docs easier to navigate. while still
letting users get code generations or AI-summarized answers if they so
wish. Also, it should reduce the cost.
Would love to hear your feedback :)
