In some cases, all the posts are not appearing under a tag. One example would be those under the Australia tag. If you notice not all posts are appearing, append ?max-results=999 at the end of the url.

So as an example, page 2 for Australia looks like: https://thisisarecordingdotcom.blogspot.com/search/label/%E2%9D%BA%20Australia?updated-max=2020-01-24T00:00:00-06:00&max-results=20&start=20&by-date=false

change the url to

https://thisisarecordingdotcom.blogspot.com/search/label/%E2%9D%BA%20Australia?max-results=999

and all posts will appear.
