Query Filtering for "Blocks" Properties

Would love to see queries upgraded to include filtering capabilities for "Blocks" properties. On a basic level, this would just include options to filter blocks that are empty or not empty, but even more so, it could filter by the number of words or even search for specific words within the blocks content.

A good example of this would be writing a blog post from a captured idea. I might have an idea for a blog post while on the go, so I create a new Blog Post object and give it a title on my phone, but then it could automatically be included in my "Blog Post Ideas" where I would filter my blog post objects where the content = empty. Many other use cases as well.
