This plugin does what it advertises very well.
However, for my purposes it needs to have better (any?) ability to exclude items from results. I understand we can enter page IDs to prevent visitors from being able to perform a live search while on a particular page, but it seems it would be far more useful (for me, anyway) to be able to exclude certain pages from being returned in the search results.
For example, I really don't want the thankyou page for filling out a form to appear in search results. Doesn't seem to be any way to prevent it with this plugin. If I'm mistaken feel free to set me straight!
Also, I AM using another plugin, Simply Exclude, that allows particular pages, posts, tagged items to be excluded everywhere else in the site. For whatever reason Dave's WordPress Live Search is ignoring whatever the Simply Exclude plugin is doing, so content I've excluded there appears within the live search results anyway.
I realize you can't please everyone, and this plugin really works very well. I'm just sad because the exclusion issue will probably be a deal-breaker for me. I hope you'll consider adding that ability in the future!
