# Drupal and Solr Chatbot Integration Guide

## Overview
This guide covers the integration of a chatbot with Drupal 10 using Solr for search functionality and controlling access and costs.

## Task List

### 1. Verify Solr Integration with Drupal
- Ensure the Solr server is running.
- Confirm that the Search API and Search API Solr modules are installed and configured in Drupal.
- Index content from Drupal to ensure Solr is indexing correctly.

### 2. Set Up Chatbot Framework
- Choose a chatbot framework (e.g., Rasa, Botpress, or OpenAI API).
- Install and configure the chatbot framework on your server.
- Connect the chatbot to Drupal via API or webhooks.

### 3. Integrate Solr with the Chatbot
- Configure the chatbot to send user queries to Solr.
- Ensure Solr returns relevant search results for the chatbot to use in responses.

### 4. Implement Access Controls
- Adjust Drupal permissions so only authenticated users can access the chatbot.
- Implement rate limiting to manage API usage and costs, either through Drupal modules or the OpenAI dashboard.

### 5. Test and Refine
- Test the chatbot by running queries and ensuring it retrieves accurate information from Solr.
- Refine configurations and adjust settings based on testing results.

## Additional Notes
- **Custom GPT vs. Self-Hosted Solution**: Using the ChatGPT interface for a custom GPT is convenient and managed by OpenAI, but costs are usage-based. A self-hosted solution gives you more control and can be more cost-effective in the long run but requires managing infrastructure.
