help:posts (locked)
A post represents a single image that's been uploaded. Each post can have many tags, comments, notes, and a single artist commentaries. Each post may also belong to multiple pools.
Searching
Searching for posts is straightforward. Simply enter the tags you want to search for, separating tags by spaces and words within tags by underscores. For example, searching for blonde_hair blue_eyes will return every post that has both the blonde hair tag and the blue eyes tag.
Be aware that tags for characters and series are sometimes known by their original Japanese names, not their English names. For example, the tag on Bleachbooru for The Melancholy of Haruhi Suzumiya is Suzumiya Haruhi No Yuuutsu. See help:tags for more information.
Bleachbooru also offers many metatags that let you further refine your search. Metatags allow you to query on things like image width, height, score, uploader, upload date, and more. Consult the cheat sheet for a complete list of what you can do.
