* LUCENE-9929: Add NorwegianNormalizationFilter, which does the same as ScandinavianNormalizationFilter except
it does not fold oo->ø and ao->å. (janhoy, Robert Muir, Adrien Grand)
* LUCENE-9981: Operations.getCommonSuffix/Prefix(Automaton) is now much more
efficient, from a worst case exponential down to quadratic cost in the
number of states + transitions in the Automaton. These methods no longer
use the costly determinize method, removing the risk of
TooComplexToDeterminizeException (Robert Muir, Mike McCandless)
* LUCENE-9981: Operations.determinize now throws TooComplexToDeterminizeException
based on too much "effort" spent determinizing rather than a precise state
count on the resulting returned automaton, to better handle adversarial
cases like det(rev(regexp("(.*a){2000}"))) that spend lots of effort but
result in smallish eventual returned automata. (Robert Muir, Mike McCandless)
* LUCENE-9944: Allow DrillSideways users to provide their own CollectorManager without also requiring
them to provide an ExecutorService. (Greg Miller)

query execution strategy and timing. (Jack Conradson, Julie Tibshirani)
