19- Searches using regular expressions or literal strings
20- Supports regex syntax like "log.*Error", "function\\s+\\w+", etc.
21- If the pattern isn't valid regex, it automatically searches for the literal text
22- Filter files by name pattern with include parameter (e.g., "*.js", "*.{ts,tsx}")
23- Automatically respects .gitignore files
24- Returns matches as "filepath:line_number: line_content""#;
