Thanks for this plugin. It does exactly what it says in the box and does it right. However, I have a little annoyance since I'm using it.
I have the parent category and the child categories, that use the parent category template.
I usually filter searches by category, such as:
Since activating the plugin, when I search a term within a child category, the search results page uses category-parent.php, instead of search.php.
When I search within the parent category, search results are rendered correctly.
