I found a great way to get improved search results on your WordPress site!
This plugin allows you to select which areas of your blog are searched and allows you to highlight the search results on your search results page (without editing your search.php file).
- Download the plugin or Search for “Search Everything” in PLUGINS _ ADD NEW
- Activate the plugin
- Set your preferences in SETTINGS _ SEARCH EVERYTHING
No need to replace or edit any code. It just takes over from the default WordPress search widget function.
