lucene version 2.4

[darul75]

hi,
first just amazing work..
I would like to use an old lucene index and not with java, so I was just trying to load my index but have faced many issue while reading it despite lucene index structure documentation.
my try https://github.com/darul75/moo/blob/master/src/solr.go a shame.. ;)
can you drive me a little I was looking at your code and codex package but I can not figure out how to change segmentsInfos.go to handle that kind of index version, mine is -7 (2.4 version)

Hi Julien, it's hard to say,as you may know, lucene is gradually evolving its index structure. I don't have much knowkedge of the old format, either. Let me have a check and get back to later.
