Description:
Fixed minor typos in the `google_imagen.ipynb` integration notebook
related to image generation prompt formatting. No functional changes
were made — just a documentation correction to improve clarity.
## **Description:**
Updated incorrect package names in `FeatureTables.js` by replacing
underscores with hyphens to reflect their actual names on PyPI. This
aligns with the actual PyPI package names and prevents potential
confusion or installation issues.
The following package names were corrected:
- `langchain_aws` ➝ `langchain-aws`
- `langchain_community` ➝ `langchain-community`
- `langchain_elasticsearch` ➝ `langchain-elasticsearch`
- `langchain_google_community` ➝ `langchain-google-community`

Description: Documentation is inconsistent with API docs.
Current documentation implies that to use the integration you must have
credentials configured AND store the path to a service account JSON
file.
API docs explain that you must only complete EITHER of the steps
regarding credentials.
I have updated the docs to make them consistent with the API wording.
## **Description:**
Refactored multiple entries in `kv_store_feat_table.py` to ensure that
all vector store metadata is accurate, consistent, and aligned with
LangChain's latest documentation structure and PyPI naming standards.
**Key improvements across all updated entries:**
- Updated `class` links to point to their respective **docs-based
integration pages** (e.g., `/docs/integrations/stores/...`) instead of
raw API reference URLs.
- Corrected `package` display names to use **hyphenated PyPI-compliant
names** (e.g., `langchain-astradb` instead of `langchain_astradb`).
- Updated `package` links to point to the **specific class-level API
references** (e.g., `/api_reference/.../storage/...ClassName.html`) for
precision.
These improvements enhance:
- Navigation experience for users
- Alignment with PyPI and docs naming conventions
- Clarity across LangChain’s integrations documentation

**TL;DR much of the provided `Makefile` targets were broken, and any
time I wanted to preview changes locally I either had to refer to a
command Chester gave me or try waiting on a Vercel preview deployment.
With this PR, everything should behave like normal.**
Significant updates to the `Makefile` and documentation files, focusing
on improving usability, adding clear messaging, and fixing/enhancing
documentation workflows.
### Updates to `Makefile`:
#### Enhanced build and cleaning processes:
- Added informative messages (e.g., "📚 Building LangChain
documentation...") to makefile targets like `docs_build`, `docs_clean`,
and `api_docs_build` for better user feedback during execution.
- Introduced a `clean-cache` target to the `docs` `Makefile` to clear
cached dependencies and ensure clean builds.
#### Improved dependency handling:
- Modified `install-py-deps` to create a `.venv/deps_installed` marker,
preventing redundant/duplicate dependency installations and improving
efficiency.
#### Streamlined file generation and infrastructure setup:
- Added caching for the LangServe README download and parallelized
feature table generation
- Added user-friendly completion messages for targets like `copy-infra`
and `render`.
#### Documentation server updates:
- Enhanced the `start` target with messages indicating server start and
URL for local documentation viewing.
---
### Documentation Improvements:
#### Content clarity and consistency:
- Standardized section titles for consistency across documentation
files.

previews.

* Adding support for more Chroma client options (`HttpClient` and
`CloundClient`). This includes adding arguments necessary for
instantiating these clients.
* Adding support for Chroma's new persisted collection configuration (we
moved index configuration into this new construct).
* Delegate `Settings` configuration to Chroma's client constructors.
## **Description:**

2. IBM watsonx.ai
3. OpenAIEmbeddings
4. NomicEmbeddings
5. CohereEmbeddings
6. MistralAIEmbeddings

The vectorstore feature table in the documentation was showing incorrect
information for the "IDs in add Documents" capability. Most vectorstores
were marked as ❌ (not supported) when they actually support extracting
IDs from documents.
## Problem
The issue was an inconsistency between two sources of truth:
- **JavaScript feature table** (`docs/src/theme/FeatureTables.js`):
Hardcoded `idsInAddDocuments: false` for most vectorstores
- **Python script** (`docs/scripts/vectorstore_feat_table.py`):
Correctly showed `"IDs in add Documents": True` for most vectorstores
## Root Cause
All vectorstores inherit the base `VectorStore.add_documents()` method
which automatically extracts document IDs:
```python
# From libs/core/langchain_core/vectorstores/base.py lines 277-284
if "ids" not in kwargs:
ids = [doc.id for doc in documents]
# If there's at least one valid ID, we'll assume that IDs should be used.
if any(ids):
kwargs["ids"] = ids
```
Since no vectorstores override `add_documents()`, they all inherit this
behavior and support IDs in documents.
## Solution
Updated `idsInAddDocuments` from `false` to `true` for 13 vectorstores:
- AstraDBVectorStore, Chroma, Clickhouse, DatabricksVectorSearch
- ElasticsearchStore, FAISS, InMemoryVectorStore,
MongoDBAtlasVectorSearch
- PGVector, PineconeVectorStore, Redis, Weaviate, SQLServer
The other 4 vectorstores (CouchbaseSearchVectorStore, Milvus, openGauss,
QdrantVectorStore) were already correctly marked as `true`.
## Impact
Users visiting
https://python.langchain.com/docs/integrations/vectorstores/ will now
see accurate information. The "IDs in add Documents" column will
correctly show ✅ for all vectorstores instead of incorrectly showing ❌
for most of them.
This aligns with the API documentation which states: "if kwargs contains
ids and documents contain ids, the ids in the kwargs will receive
precedence" - clearly indicating that document IDs are supported.
Fixes#30622.

- **Description:** This PR updates the `package` field for the VertexAI
integration in the documentation metadata. The original value was

`langchain-google-vertexai` to reflect the actual package name used in
PyPI and LangChain integrations.

- **Description:** Corrected the `link` path in the Google Gemini
integration entry from
`/docs/integrations/text_embedding/google-generative-ai` to
`/docs/integrations/text_embedding/google_generative_ai` to align with
actual directory structure and prevent broken documentation links.

Description
The Perplexity chat model already returns a search_results field, but
LangChain dropped it when mapping Perplexity responses to
additional_kwargs.
This patch adds "search_results" to the allowed attribute lists in both
_stream and _generate, so downstream code can access it just like
images, citations, or related_questions.
Dependencies
None. The change is purely internal; no new imports or optional
dependencies required.

Before jumping into tech implementation, I added a context for
linearization-config param, and explained what's linealization in this
context.
I also linked an AWS blog for more advanced use cases, as this single
example doesn't cover all use cases.

**On this PR I am doing two things:**
1. Adding titles to the 4 example we have, to allow the reader to
capture the essence of the paragraph quickly
2. Replacing 'samples' with 'examples', for more clarity,
**Why 'examples' could be a better terminology over 'samples' here?**
1. On the page, we were using both 'samples' and 'examples'
interchangeably which lead to confusion, now 'examples' are the use
cases, while 'samples' are the the sample data being used
2. This is consistent with the rest of the docs, we typically use
'examples' for examples, for example
