Alan Woodward commented on LUCENE-8646:
---------------------------------------
Here's a patch with one possible implementation. It adds support for prefix
and wildcard expansions, and limits both to 128 terms. Expansion is done
per-leaf reader (no rewriting) which I think is fine as we're not aggregating
term stats or anything, so there's no need for a global view. I haven't added
support for Regexp-type intervals as the API starts getting very clunky; we
might want to revisit the Regexp object API itself, or maybe add the ability to
build intervals directly from an Automaton.

> We currently have no support for wildcard-type intervals. I'd like to
> explore adding some very basic support for prefix and wildcard interval
> sources, but we need to ensure that we don't end up with the same performance
> issues that dog SpanMultiTermQueryWrapper.
