<br>This pull-request includes code changes to use the new index/query api in Lucene 4.8.0.<br>
(I called jsword release.version = 2.0.1-luceneupgrade-alpha)<br>It uses LUCENE_30 version (set in IndexMetadata.LUCENE_IDXVERSION_FOR_INDEXING) in IndexWriter/QueryParser for compatibility.<br>After a transition phase, I am thinking we will switch this version to latest (to use newer features, less RAM usage in newer index format).<br>
<br>As far as I could test, it seem to be back compatible to existing index when using LUCENE_30. We need folks to test this for european/asian language bibles using existing index (since English is using SimpleLuceneAnalyzer with no stemming etc it is unlikely to have issues in English bible index).<br>
<br>All feedbacks/testing efforts are very much appreciated.<br>/sijo<br><br><br></div><div class="gmail_extra"><div><div class="h5"><br><br><div class="gmail_quote">On Thu, May 8, 2014 at 12:36 AM, Sijo Cherian <span dir="ltr"><<a href="mailto:sijo.cherian@gmail.com" target="_blank">sijo.cherian@gmail.com</a>></span> wrote:<br>

The 4.x lets you read older version index upto 3.0. If I can figure out difference between 2.9 vs 3.0 version, then we can decide if a hop to lucene 3.6 is necessary.
