[jsword-devel] New Search Syntax

Is the intention of RangeNotation that it should be strictly a VerseRange,
i.e. a set of contiguous verses in the Bible? If so we are missing being
able to restrict searches by doing: [ Dan, Rev ], which we could do if it
were a Passage.
I've been surprised before about the lack of i18n in Lucene. I notice that
google does allow word based connectors (as well as punctuation ones) but
only if they are in capitals. I looked because I was going to say "do we
need word based connectors". Not that we need it because Google do though.
I still tend towards thinking that word based connectors drag up more
problems than they solve though.
- Does [ Gen to Mal ] now mean the same as [ Gen - Mal ]
- Which words to we allow for "Joseph - Mary": "Joseph without Mary" or
"Joseph but not Mary"
- What then if someone wants to use without in a search.
Do we have an option in Lucene to use only punctuation based connectors?
