WordPress Combined Searches

Some useful WordPress URL tricks I’ve discovered for combining tag and category searches. You can search for…

The intersection of two tags

/tag/first-tag+second-tag

The union of two tags

/tag/first-tag,second-tag

The subset of posts in a category that also have a tag

/category/some-category?tag=some-tag

Posts by an author in a category

?author_name=whoever&category_name=some-category

A post format within a category

/category/some-category?post_format=link

/category/some-category?post_format=image

…and so on. You can look up more parameters in the WP_Query documentation and try combining them into more complex search/archive terms.
