The query builder does currently not show the built query in the search box. This is a missed opportunity for teaching people how to achieve the query with direct search syntax. It is also confusing, because the query builder does not have a Submit button, but the "Search" submit button is implied to submit what is in the search box, not the query builder.

I propose it makes the search box readonly and updates its contents.
Let's get more user feedback on the query builder before prioritizing/making this change. There is one other direction (that I consider fairly likely) that would preclude this specific change:
Adding @francisschmaltz for user research on this.
Personally I am -1 on that because it makes the UI less clean/tidy.
But I think it would be good idea to remember the open state in localStorage for people who always prefer the query builder
I agree with Felix that it shouldn't be always visible. The 1 way binding we previous discussed would be the right thing to do here.
Query builder is feature flagged off by default and will be removed, so closing.
