# Task
Using https://lancedb.github.io/lancedb, complete the following task:

Using LanceDB, build me a FAQ search system:

1. Store these 3 FAQs:
   - Q: "How do I reset my password?" A: "Go to Settings > Security > Reset Password"
   - Q: "How do I cancel my subscription?" A: "Go to Settings > Billing > Cancel Plan"
   - Q: "How do I update my email?" A: "Go to Settings > Profile > Edit Email"

2. Search for: "I can't log into my account"

3. Print the best matching FAQ and its similarity score 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
