WPMU/WordPress Network is very awesome. But when I first heard of the concept – I was like…”yes, a killer way to a have a blog network in which the ‘parent’ blog could rollup all blogs…” – well, not quite. I want to do one search with WPMU/WordPress Network – across the whole thing.
The One Search plugin takes a crack at this…
Rather than relying on PHP to build complex queries at run-time, which can slow page processing, The One Search WPMU Plugin uses MySQL views. When new blogs are added, the view is automatically updated. End-user searches are then redirected from the individual blog tables and pointed to the appropriate MySQL views.
See what you think.
