api.tumblr.com/v2/blog/{blog-identifier}/posts/{type}?tag= incorrect `total_posts`

Follow-up to https://github.com/tumblr/docs/issues/54

The bug was fixed last month to report the correct total_posts when filtering by tag:

https://api.tumblr.com/v2/blog/derekmd.tumblr.com/posts?tag=Villa+Amanzi

• response.total_posts = 1 :heavy_check_mark:
• response.blog.posts = 2
• response.blog.total_posts = 2

Filtering by post type also counts as expected:

https://api.tumblr.com/v2/blog/derekmd.tumblr.com/posts/photo

• response.total_posts = 2 :heavy_check_mark:
• response.blog.posts = 2
• response.blog.total_posts = 2

https://api.tumblr.com/v2/blog/derekmd.tumblr.com/posts/text

• response.total_posts = 0 :heavy_check_mark:
• response.blog.posts = 2
• response.blog.total_posts = 2

---

However if the post type filter is also included in the URL alongside tag filtering, the total_posts count is for the blog's unfiltered results:

https://api.tumblr.com/v2/blog/derekmd.tumblr.com/posts/photo?tag=Villa+Amanzi

• response.total_posts = 2 :x: (this should be 1 like above)
• response.blog.posts = 2
• response.blog.total_posts = 2

https://api.tumblr.com/v2/blog/derekmd.tumblr.com/posts/text?tag=Villa+Amanzi

• response.total_posts = 2 :x: (this should be 0)
• response.blog.posts = 2
• response.blog.total_posts = 2

Thanks for writing in about this! Unfortunately this is expected behavior right now, as the filter-by-tag(s) option can be accurately counted at request time, but doing more than one kind of filtering (in this case, by tag and by type) cannot be accurately counted. I'll add a clarifying note about this in the docs, and we'll see if we can make this better on the backend.
