Search Everything is a plugin designed to significantly enhance the default search functionality of WordPress. This tool allows users to search through a wide array of content types, including pages, excerpts, attachments, comments, tags, and custom fields, without altering any template pages. Users can also customize their search highlight style and exclude specific pages or posts from search results. Importantly, it does not index password-protected content, ensuring that sensitive information remains secure.

In addition to its core features, Search Everything introduces a writing helper called Research Everything, which enables users to search for and link to their own posts while crafting new content. The plugin also includes a Power Search option for broader web research, available for WordPress versions 3.7 and above. The straightforward setup process involves activating the plugin, configuring options, and beginning searches, making it accessible for WordPress users seeking improved search capabilities.
