Description
Checked other resources
- I added a very descriptive title to this issue.
- I searched the LangChain documentation with the integrated search.
- I used the GitHub search to find a similar question and didn't find it.
- I am sure that this is a bug in LangChain rather than my code.
Example Code
from langchain.vectorstores.elasticsearch import ElasticsearchStore
from langchain.embeddings.huggingface import HuggingFaceBgeEmbeddings
from langchain.chains.query_constructor.base import AttributeInfo
from langchain.retrievers.self_query.base import SelfQueryRetriever
from langchain.chat_models.openai import ChatOpenAI
vectorstore = ElasticsearchStore(
embedding=HuggingFaceBgeEmbeddings(
model_name="BAAI/bge-small-en-v1.5",
model_kwargs={"device": "cpu"},
encode_kwargs={"normalize_embeddings": True},
),
index_name="z-index",
es_url="http://localhost:9200",
)
metadata_field_info = [
...,
AttributeInfo(
name="update_date",
description="Date when the document was last updated",
type="string",
),
...
]
document_content = "an abstract of the document"
retriever = SelfQueryRetriever.from_llm(
ChatOpenAI(temperature=0, api_key=KEY, max_retries=20),
vectorstore,
document_content,
metadata_field_info,
verbose=True,
enable_limit=True
)
r = retriever.invoke("give me all documents in the last two days?")
print(r)Error Message and Stack Trace (if applicable)

Description
The ElasticsearchTranslator should not put comparison value in the field directly since it cause a syntax error in the query, instead if it's a date it should put the value of the date (just like in the issue #16022)
