Omnisearch: one search box, global results. Don’t waste time digging for that one comment with the useful link — or was it a post you saw it in? Search once and get results from all of your posts, pages, comments, and feedback.
Using Omnisearch is remarkably easy. Just search!
When you’re in your WordPress.com blog dashboard, simply type in a search term and Omnisearch will show you results from posts, pages, comments, and feedback. On the right hand side you can toggle between the different search sections.
Please note that the Search field on the WordPress Admin Bar will only Omnisearch from the back-end of your site, as the front-end already has a search field there to perform a site search natively, and we didn’t want to change that for you.
