# Code Search The built-in `grep` tool matches LITERAL text only. For real regular-expression search and history-aware lookups, drive ripgrep and git through `execute`. ## Ripgrep (regex) - Symbol definition: `rg -n "fn\s+\w+\(" src/`, `rg -n --type java "class \w+Service"`. - Usages of a name: `rg -n "\bmyFunction\b"`. - Limit by file type: `rg -n --type ts "useEffect\("`. - List files only: `rg -l "TODO"`; find files by name: `rg --files | rg <name>` or use `glob`. ## Git history search - When a string was introduced/removed: `git log -S "<string>" --oneline`. - Who/why a line changed: `git blame -L <start>,<end> <file>`. - Search tracked files: `git grep -n "<regex>"`. ## Tips - Prefer a targeted regex over reading whole files when locating symbols or call sites. - Escape regex metacharacters when you want a literal match, or pass `-F` to ripgrep. - Narrow scope with a path argument to keep output small (tool output is truncated).
