-------------------------------------
Summary: Intervals.multiterm() should take a CompiledAutomaton
Key: LUCENE-9212
URL: https://issues.apache.org/jira/browse/LUCENE-9212
Project: Lucene - Core
Issue Type: Improvement
Reporter: Alan Woodward
Assignee: Alan Woodward
LUCENE-9028 added a `multiterm` factory method for intervals that accepts an
arbitrary Automaton, and converts it internally into a CompiledAutomaton. This
isn't necessarily correct behaviour, however, because Automatons can be defined
in both binary and unicode space, and there's no way of telling which it is
when it comes to compiling them. In particular, for automatons produced by
FuzzyTermsEnum, we need to convert them to unicode before compilation.
The `multiterm` factory should just take `CompiledAutomaton` directly, and we
should deprecate the methods that take `Automaton` and remove in master.
