Multisite Search Plugin for WordPress

A minimal WordPress plugin that enables searching across all sites in a multisite installation by integrating with the native WordPress search functionality.

Features

Native Integration: Works with existing WordPress search forms and functionality
Cross-Site Search: Automatically searches across all enabled sites in the network
Simple Configuration: Basic admin settings to control which sites are included
No Custom UI: Uses existing WordPress search forms and results pages

Installation

Upload the multisite-search.php file to your /wp-content/plugins/multisite-search/ directory
Activate the plugin through the 'Plugins' menu in WordPress
Configure settings in Settings > Multisite Search (for individual sites) or Network Admin > Settings > Multisite Search (for network-wide settings)

Usage

Once activated, the plugin automatically modifies WordPress search queries to include results from all enabled sites in your multisite network. Users can use any existing search form on your sites, and results will include content from across the network.
