## What it is
A Vim plugin that improves incremental searching by highlighting all pattern matches as you type, including live regular expression editing. It is now deprecated because its core functionality was merged into Vim/Neovim itself.

## Use cases
- highlight all regex matches incrementally while searching in vim
- see live regex match preview while typing a search pattern
- automatically turn off hlsearch after searching
- improved / and ? search behavior in vim
- incremental search that works in visual and operator-pending modes

## When to choose
- you are stuck on a very old Vim version without built-in incsearch highlighting
- you need the incremental regex editing preview on legacy editors

## When to avoid
- you use a modern Vim or Neovim, which includes this functionality natively
- you want an actively maintained plugin - use the successor is.vim instead

## Facets
- artifact type: plugin
- maturity: abandoned
- function: search-engine, developer-tools
- domain: text-editors, developer-tools
- platform: editor-plugin, cli
- tags: vim-plugin, incremental-search, regex-highlighting, deprecated
