Adrien Grand commented on LUCENE-7880:
--------------------------------------
This is not the only arbitrary limit we have. For instance terms can't be
greater than 32KB and you can only use edit distances of 1 or 2 with FuzzyQuery.
In some of the cases you mentioned, it seems to me that users should be using
TermInSetQuery instead. Maybe a few of them actually need scoring, which is
only provided by BooleanQuery. However, to me those are corner cases, and I
don't like the idea of extending the API of an important class like
BooleanQuery just to help deal with corner-cases.
To me the best option is to keep things as they are today: let users know when
they are using BooleanQuery in ways that won't perform well, yet still allow a
minority of corner-cases that need greater limits to increase the max clause
count through the static setter.

> As we know, the magic BooleanQuery.maxClauseCount has bitten many people over
> time.
> It's also a static, which really hurts multi-tenancy (i.e. we can't have
> different settings for different users, clients, or use-cases).
> If we want to keep this static as a default, then at least we should allow it
> to be overridden on a per-query basis when we know it is the desired behavior
> and not a bug.
> Perhaps the simplest way to achieve this would be a setter on
> BooleanQuery.Builder that configures the limit for that instance only?
