Vim's search functionality is very powerful, supporting various search patterns and techniques. Basic search: /pattern to search forward, ?pattern to search backward, n for next match, N for previous match. Search options: \c to ignore case, \C to match case, \b for word boundary, \e to match end of line, \s to match whitespace. Regular expression search: supports . * [ ] ^ $ and other regex metacharacters. Highlight settings: :set hlsearch to highlight all matches, :set nohlsearch to cancel highlighting, :noh to temporarily turn off highlighting. Search history: press up/down arrows after / or ? to browse history. Special character search: use \ to escape special characters. Multi-file search: :vimgrep /pattern/ **/*.py to search across multiple files. Search navigation: * to search for word under cursor, # to search backward for word under cursor. Mastering these search techniques can greatly improve efficiency in finding and locating content in Vim.
