**Description:**
#18040 forces `fastembed>2.0`, and this causes dependency conflicts with
the new `unstructured` package (different `onnxruntime`). There may be
other dependency conflicts.. The only way to use
`langchain-community>=0.0.28` is rollback to `unstructured 0.10.X`. But
new `unstructured` contains many fixes.
This PR allows to use both `fastembed` `v1` and `v2`.
How to reproduce:
`pyproject.toml`:
```toml
[tool.poetry]
name = "depstest"
version = "0.0.0"
description = "test"
authors = ["<dev@example.org>"]
[tool.poetry.dependencies]
python = ">=3.10,<3.12"
langchain-community = "^0.0.28"
fastembed = "^0.2.0"
unstructured = {extras = ["pdf"], version = "^0.12"}
```
```bash
$ poetry lock
```

- **Description:** This modification addresses the issue of mutable
default parameters in functions. In the original code, the `chunks`
parameter is defaulted to a list containing an empty dictionary, which
is mutable. Since default parameters in Python are evaluated only once
at function definition time, modifications to the parameter would
persist across future calls. By changing the default to `None` and
checking/initializing within the function, a new list is created for
each call, thus avoiding potential issues.

## Description
This PR addresses a documentation issue in the
[Indexing](https://python.langchain.com/docs/modules/data_connection/indexing)
page. Specifically, it corrects the execution results of the Jupyter
notebook under the
[Source](https://python.langchain.com/docs/modules/data_connection/indexing#source)
section, which were broken as detailed below.
## Problem
The execution results following the statement, `This should delete the
old versions of documents associated with doggy.txt source and replace
them with the new versions.`, appear to be incorrect, as described
below.
### Current Behavior
- For some reason, the `index` function fails to add the new content of
`doggy.txt`. Although it deletes the document objects associated with
the `doggy.txt` source, it does not add the objects in
`changed_doggy_docs`. Consequently, the execution result displays
`num_added: 0`.
- This unexpected behavior also impacts the results of
`vectorstore.similarity_search("dog", k=30)`, showing only the contents
of `kitty.txt`. It appears as though the contents of `doggy.txt` have
been completely removed from the index:
```
Document(page_content='tty kitty', metadata={'source': 'kitty.txt'}),
Document(page_content='tty kitty ki', metadata={'source': 'kitty.txt'}),
Document(page_content='kitty kit', metadata={'source': 'kitty.txt'})]
```
### Expected Behavior
- The `index` function should successfully add the objects in
`changed_doggy_docs` after removing the old content of `doggy.txt`. The
anticipated execution result is `num_added: 2`.
- Subsequently, the modified content of `doggy.txt` should appear in the
results of `vectorstore.similarity_search("dog", k=30)` as follows:
```
[Document(page_content='woof woof', metadata={'source': 'doggy.txt'}),
Document(page_content='woof woof woof', metadata={'source': 'doggy.txt'}),
Document(page_content='tty kitty', metadata={'source': 'kitty.txt'}),
Document(page_content='tty kitty ki', metadata={'source': 'kitty.txt'}),
Document(page_content='kitty kit', metadata={'source': 'kitty.txt'})]
```
## Fix
I reran `docs/docs/modules/data_connection/indexing.ipynb` and have
included the diff in this PR.

@eyurtsev PTAL
Docs fix: replace column name search with source.
The Xata integration expects metadata column named "source".
The docs suggest the name "search", which if used, yields the following
error:
```
File "/usr/local/lib/python3.11/site-packages/langchain_community/vectorstores/xata.py", line 95, in _add_vectors
raise Exception(f"Error adding vectors to Xata: {r.status_code} {r}")
Exception: Error adding vectors to Xata: 400 {'errors': [{'status': 400, 'message': 'invalid record: column [source]: column not found'}]}

poetry can't reliably handle resolving the number of optional "extended
test" dependencies we have. If we instead just rely on pip to install
extended test deps in CI, this isn't an issue.

This PR makes the following updates in the pgvector database:
1. Use JSONB field for metadata instead of JSON
2. Update operator syntax to include required `$` prefix before the
operators (otherwise there will be name collisions with fields)
3. The change is non-breaking, old functionality is still the default,
but it will emit a deprecation warning
4. Previous functionality has bugs associated with comparisons due to
casting to text (so lexical ordering is used incorrectly for numeric
fields)
5. Adds an a GIN index on the JSONB field for more efficient querying
**PR message**: ***Delete this entire checklist*** and replace with
