Filter tags with descriptions

Hi there, I’m trying to output a list of all site tags that have a description. This doesn’t work (I get nothing)… What am I missing?

{{#get 'tags' limit='all' filter='-tags.description:null' include='count.posts' order='count.posts desc'}}

On a similar note, this doesn’t work either (trying to get all tags that have at least one post)

{{#get 'tags' limit='all' filter='count.posts:>=1' include='count.posts' order='count.posts desc'}}

Thanks!

For your first query, try this: filter="description:-null"

For your second query, not being able to filter by count.posts is a current limitation of the get helper

great - thanks
