# Web Explorer
This is a lightweight app using the [Web Research Retriever](https://github.com/langchain-ai/langchain/pull/8102).
## Setup
You only need to supply a few things.
In `settings()` function, supply:
* Search: Select the search tool you want to use (e.g., GoogleSearchAPIWrapper).
* Vectorstore: Select the vectorstore and embeddings you want to use (e.g., Chroma, OpenAIEmbeddings).
* Select the LLM you want to use (e.g., ChatOpenAI).
To use `st.secrets` set enviorment variables in `.streamlit/secrets.toml` file.
Or, simply add environemnt variables and remove `st.secrets`:
```
import os
os.environ["GOOGLE_API_KEY"] = "YOUR_API_KEY"
os.environ["GOOGLE_CSE_ID"] = "YOUR_CSE_ID"
os.environ["OPENAI_API_BASE"] = "https://api.openai.com/v1"
os.environ["OPENAI_API_KEY"] = "YOUR_API_KEY"
```
For `GOOGLE_API_KEY` , you could get it from [this link](https://console.cloud.google.com/apis/api/customsearch.googleapis.com/credentials).
For `GOOGLE_CSE_ID` , you could get it from [this link](https://programmablesearchengine.google.com/)
