Frequently Asked Questions
Why this plugin is useful for users of your blog?
It’s useful because they can easily check what themes you writing for, and this way they could find the desired article more easily.

Too bad this handy plugin busts my preview feature on comments (while using Sexy Comments as plugin for that). So I deactivated this plugin.
Running WP 2.7 beta 3 btw…
Thanks… Nice Plugin…
For anyone that wants to autocomplete post titles instead of tags, I rewrote the sql query to compensate.
Under values.php:
Replace the select query with:
“SELECT post_title FROM wp_posts WHERE post_title LIKE ‘$search%’ AND post_status LIKE ‘%publish%’”
Replace: echo $word->name.”\n”;
with
echo $word->post_title. “\n”;
Thanks for a great plugin. =) Happy searching!
This pretty much just asks for post_title’s that are published so as not to spam the list with the revisions. After all we only need the title. This also removes the media files from the search box as well, because they are posted as inherit.
Thanks for the update snetErz. Although I don’t think that the idea of search is to make autocomplete of the posts.
The reason why I think this way is simple - autocompleter is just a guide (helper) which will help users to find relevant information. Tags and categories are exactly this.
Anyway, your comment will be here, so anyone who want to use it with your approach is more welcome
Cheers
