The main changes in Lucene 3.0 was the new token stream api . But
this was introduced in Lucene 2.9. However, one class has been renamed
(CharTermAttribute) differently in Lucene 3.0 which breaks compilation.
When I try to compile siren-core using lucene 2.9.4, I get errors like
This is something to modify in order to make SIREn compatible with
lucene 2.9.*. There are also all the Lucene Version flags (i.e.,
LUCENE_31) to change back to LUCENE_29.
The rest of siren-core and siren-parser should work. Concerning
siren-solr, I don't exactly know what were the modifications, but I
think they were minimal.
I hope this helps, let me know if you need more information. I could
also provide you the source code of SIREn before the upgrade to Lucene
3.0. This might helps you understanding what needs to be changed.
