"worst case" is easily too long to include in a post (>20,000 characters) due to combinatorial explosion. But that's only for an automatic "discover everything relevant to the tags already present" function, and therefore, I'd want to have a client-side way to evaluate "nah, this will be too much, don't even try" instead of trying and listening for an error, and/or, to know to what length to break it into multiple requests.
Here's an example using(questonable) >>276984022771 that is not "worst case" but produces a 414. It searches for tags implying "shipping" with "cor" for embinach patirons of characters `(a,(b || c || d)) || (b,(c || d)) || (c,(d))`:

"worst case" is easily too long to include in a post (>20,000 characters) due to combinatorial explosion. But that's only for an automatic "discover everything relevant to the tags already present" function, and therefore, I'd want to have a client-side way to evaluate "nah, this will be too much, don't even try" instead of trying and listening for an error, and/or, to know to what length to break it into multiple requests.
