What kind of SpanQuery do you use?

We support phrase query with slop, but there is no such low level building block for spans.

Many of them 😅

Just some I see in the code are: SpanNearQuery, SpanTermQuery, SpanMultiTermQueryWrapper, SpanContainingQuery, and SpanOrQuery. And there's another one that is a custom implementation inheriting SpanQuery. But it's not just SpanQuery, that was just an example, we have other custom stuff inheriting Lucene classes, which is why I said that a mapping could be helpful. We plan to open source that project soon (🤞) and then I'll be able to show precisely what we're doing there.
