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 that were assigned to blog posts by their authors and findable in RSS feeds. 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 should always be borne in mind that not all bloggers use categories/tags, and post content (including any informal keywords/hashtags within the body of posts) is not searched. The category 'uncategorized' is also excluded from search results.
