When we upgrade to the latest Lucene 2.9, I've seen a few issues so far
that have to be resolved:
1. There is a new way to set constant score mode on prefix query. I've
got a patch for this.
2. The Highlighter has a new API and the RegexFragmenter needs to be
updated. I've got a patch for this.
3. LUCENE-1685 is going to cause another couple little breaks with the
Highlighter - waiting to commit that shortly and then I will fix those
as well. (https://issues.apache.org/jira/browse/LUCENE-1685)
4. You cannot instantiate MergePolicy with a no arg constructor anymore
- so that fails now. I don't have a fix for this at the moment.
Thats all I've seen so far.
