How to do this search...

I want to see what chartags are under a property. I don't need to see the images, just a list of chartags. I'd also like to be able to order them, like in descending or ascending order of post count.

Try this page out, it's not perfect but it's very good.

Character tags aren't tied to copyrights directly, so what you're asking for isn't possible as a database query per se.

That said, in addition to the related tags page above, many of the larger copyrights on the site have wiki pages under the naming format "list_of_*_characters", for example: list of genshin impact characters.

Adding onto what Obstetrics said, you CAN actually search the tags by their existence in a particular wiki page and order them by post count.

https://danbooru.donmai.us/tags?search[dtext_links][model_id]=93250&search[dtext_links][model_type]=WikiPage&search[order]=count&search[category]=4&search[hide_empty]=false

I'll point out some things with the above link so that others can template off it.

• search[dtext_links][model_id]=93250 - Change this value to the ID of the wiki to be checked.
• For example, the above value is the List of Girls und Panzer characters wiki ID.
• Both the Edit and History links include the wiki ID.
• search[dtext_links][model_type]=WikiPage - Required, unless you want to get hits from Forum Posts of the same ID.
• search[order]=count - Orders the tags by post count.
• Check API:Tags for a list of other values.
• search[category]=4 - Set for character tags only as requested.
• Check API:Tags for a list of other values.
• search[hide_empty]=false - Optional if one wants to see empty tags (post count is zero).
• Otherwise change the value to true.
