Notes

• Email content is extracted from text/plain or stripped from text/html
• Special characters and encoding issues are handled with UTF-8 fallback
• Search uses Gmail's query language (same as Gmail web search)
• Snippets are truncated to ~100-150 characters
• Full email body is retrieved when using get command
