> while working on OAK-6069 i noticed that there exist IMO troublesome dependencies from _o.a.j.oak.spi.query_ back to _o.a.j.oak.query.*_. While i don't know the historical reasons that led to this setup it feels wrong to me that the interfaces and classes in _o.a.j.oak.spi.query_ would have dependencies to packages that from my understanding are supposed to contain implementations.
> while utilities like {{o.a.j.oak.spi.query.Cursors}} may simply have ended up in the wrong bucket and could possibly moved to e.g _o.a.j.query.index_, i couldn't find an easy solution for an interface like  {{o.a.j.oak.spi.query.Filter}} that defines methods returning {{o.a.j.query.fulltext.FullTextExpression}} and {{o.a.j.query.QueryEngineSettings}}, while at the same time being tied to the {{o.a.j.oak.spi.query.QueryIndex}} interface.
