Subject Re: Lucene version compatibility
Date Thu, 30 Oct 2014 13:13:50 GMT
Thanks, but as soon as it is changed to anything higher (I've tried 4.7, 4.8, 4.9, and 4.10.1)
then compilation errors result. For example, using 4.10.1 (LUCENE_4_10_1) the following errors
are observed (these are different depending upon which version is used):
