llama-index readers opensearch integration

Opensearch Loader

The Opensearch Loader returns a set of texts corresponding to documents retrieved from an Opensearch index. The user initializes the loader with an Opensearch index. They then pass in a field, and optionally a JSON query DSL object to fetch the fields they want.

Usage

Here's an example usage of the OpensearchReader to load 100 documents.

from llama_index import download_loader

OpensearchReader = download_loader("OpensearchReader")

reader = OpensearchReader(
    host="localhost",
    port=9200,
    index="<index_name>",
    basic_auth=("<user_name>", "<password>"),
)

query = {"size": 100, "query": {"match_all": {}}}
documents = reader.load_data(
    "<field_name>", query=query, embedding_field="field_name"
)

This loader is designed to be used as a way to load data into LlamaIndex and/or subsequently used as a Tool in a LangChain Agent. See here for examples.
