Search post categories/tags used by blogs listed at this site.
By default, this searches for any categories containing your search term: eg, Tudor will also find Tudors, Tudor History, etc. Check the 'exact' box to restrict searching to categories exactly matching your search. All searches are case-insensitive.
This is a search for tags/categories assigned to blog posts by their authors. The terminology used for post tags varies across different blog platforms; for example, WordPress tags and categories, Blogspot labels, and Tumblr tags are all included. However, blog.com (blog.co.uk, blog.de etc) tags are not included, because they don't appear in the blogs' RSS feeds.
It does not search post content, and it will not find any informal keywords/hashtags within the body of posts. The category 'uncategorized' is excluded from search results and it should always be borne in mind that not all bloggers use categories/tags.
