llama-index packs agent_search_retriever integration

Agent-Search Retrieval Pack

This LlamaPack creates a custom retriever that uses the agent-search API for retrieving general content indexed from the internet.

This framework facilitates seamless integration with the AgentSearch dataset (terabytes of indexed data!) or hosted search APIs (e.g. Search Engines).

During query-time, the user passes in the query string, search provider (bing, agent-search), and relevant nodes are retrieved from the hosted dataset.

To learn more, please refer to the documentation here.

CLI Usage

You can download llamapacks directly using llamaindex-cli, which comes installed with the llama-index python package:

llamaindex-cli download-llamapack AgentSearchRetrieverPack --download-dir ./agent_search_pack

You can then inspect the files at ./agent_search_pack and use them as a template for your own project!

Code Usage

You can download the pack to a the ./agent_search_pack directory:

# Optionally set the API key in the env
# import os
# os.environ["SCIPHI_API_KEY"] = "..."

from llama_index.core.query_engine import RetrieverQueryEngine
from llama_index.core.llama_pack import download_llama_pack

# download and install dependencies
AgentSearchRetrieverPack = download_llama_pack(
    "AgentSearchRetrieverPack", "./agent_search_pack"
)

agent_search_pack = AgentSearchRetrieverPack(
    api_key="...", similarity_top_k=4, search_provider="agent-search"
)

# use the retriever directly
retriever = agent_search_pack.retriever
source_nodes = retriever.retrieve("query str")

# uses the agent-search retriever within a llama-index query engine!
query_engine = RetrieverQueryEngine.from_args(retriever)
response = query_engine.query("query str")

The run() function is a light wrapper around retriever.retrieve().

source_nodes = agent_search_pack.run("What can you tell me about LLMs?")

print(source_nodes)
