WPMU DEV Post Indexer 3.0.6.4
Wordpress Plugins WPMU DEV 4.8 (1.3K reviews)
On a WordPress multisite network, every site normally keeps its own posts in its own database tables. That arrangement makes a search box on one site blind to content on any other site, which becomes awkward when the network is supposed to feel like a single connected space. WPMU DEV Post Indexer changes that by building a central index from posts across the sites you choose to include. It scans those sites, reads their post data, and stores it in one indexed location. After that, any theme, plugin, or custom script can query the index and retrieve content from many sites at once. The plugin was created by WPMU, a developer with a long history in the WordPress ecosystem, and it runs without adding any visible interface for regular users. Instead, it works quietly behind the scenes, giving administrators a way to open up network-wide content discovery.
The plugin gives administrators direct control over what gets included. You can index every site on the network, or you can pick just a handful. That flexibility matters when some sites are test environments, private client areas, or simply not relevant to the main search experience. Once you make your selection, the indexer processes the sites one at a time instead of trying to handle everything at once. This sequential approach keeps server load low and helps avoid timeouts on shared hosting. You can also run the indexer manually on a single site, which comes in handy when you want to bring a newly added site into the network index. Existing posts are picked up immediately, and new posts are added automatically after that. From then on, the plugin watches for new content and updates the index in the background, so the shared data stays current without any ongoing effort from an administrator.

The most obvious benefit is network-wide search. With the index in place, a search form on any included site can return results from across all of them. That opens up a genuinely unified content experience. A company with separate sites for each product line can let customers search every product page from a single search box. A media network can show related articles from sister publications. A multi-author blogging community can offer one listing of recent posts no matter which blog they came from. The index also makes cross-site sharing easier. You can pull a post from one site and display it on another without duplicating the entry, and developers can write custom loops that fetch posts from multiple sites at once because the index behaves like a simple data source. That shared asset becomes available to any theme or plugin you install, turning a scattered collection of independent sites into a connected, searchable network.
This is not a flashy plugin. It adds no widgets, no shortcodes, and no menu items for normal users. Its purpose is purely architectural. It extends the WordPress database with an index that other code can rely on, making it a tool for site administrators and developers who want to build features on top of a shared content foundation. You need to run WordPress Multisite, and you need network admin access to choose which sites are included. Because the index only covers sites you explicitly select, private or restricted parts of your network remain outside the shared results, giving you control over what becomes visible network-wide. WPMU built the plugin to support its own suite of products, but it stands alone as a practical utility for any multisite project. It performs its job steadily and quietly, and once set up, it keeps working without constant attention, which is especially valuable on large networks with many moving parts.
