By default, WordPress is setup to search every post. What they don’t tell you is that doesn’t include pages. However, with the Search Everything plugin, you can search pages, posts and more.
No only will Search Everything allow you to include pages in your WordPress search, but also comments, drafts, attachments and custom meta fields. You get to choose what extra fields you want to include which is good as I have no idea why you’d want to include drafts or un-approved comments.
This is really handy for those that use WordPress as their website content management system. I’ve used WordPress not as a blogging platform, but as an easy content management source. Some sites have more pages than posts and searching proves problematic.
Even if you use WordPress for blogging, like most do, there is probably a good chance that you’ve created some pages. Maybe an about page, content, resources or one of many options. And, all those pages deserve to be part of the internal search.
By installing the Search Everything plugin, not only will the search box look though posts, but pages also and give your visitors better results.
