How to search for more tags?

[Natenom]

The advanced search form implies it is possible to add several tags, categories, authors, etc.

How would I search for two tags?

Tried "tag 1", "tag " but it does not work even if both tags are used in a blog post.

The AND operation for taxonomies(tags, categories...) is unsupported on current implementation. You can request a new feature if you need this feature, I'll find time to implement it.

BTW, OR operation is supported, such as CSS | Alert matches CSS or Alert.

Implemented #679.
