    Description

      I'm not sure about the way that order in SelectFS is handled. Naively, I would expect that all operations return annotations in index order or in reverse index order if `backwards` was called. But for example `jcas.select(Sentence.class).between(t1, t2).asList()` returns in normal order if `t1 < t2` and in backwards order if `t2 < t1`. While I this seems to be a nice touch from the engineering point of view, from a naive user's perspective, it seems somewhat surprising to me. Mind that the behavior is documented - still I wonder it if is a good idea. If I wanted to have the annotations in reverse order, I'd probably try calling `jcas.select(Sentence.class).backwards().between(t1, t2).asList()` or maybe `jcas.select(Sentence.class).between(t1, t2).backwards().asList()`.
