Review Comment:
It's a great question! Maybe we could pass it as a constructor parameter,
and the constant `RewriteMethod`s in `MultiTermQuery` could specify the default?
I host a weekly OpenSearch Lucene Study Group on Zoom and we spent this
week's meetup talking about this PR (and your issue):
https://forum.opensearch.org/t/opensearch-lucene-study-group-meeting-monday-march-25th-2024/18547/3
There were some nice ideas that came up there around how to pick something
better than an arbitrary limit -- like maybe using a time threshold instead.
(But would that be a threshold per-clause?)
