Hey Menaka! The Lucene code has just been committed to master. We came up with a list of incremental issues that you can solve over the summer as you work through this project. I made a Wiki page where we can track the progress of the project as the summer progresses. It also includes an example of Lucene XPath indexing that will be helpful when starting: https://cwiki.apache.org/confluence/display/VXQUERY/Lucene+Indexing+Project+2016
I am excited to start working with you on this. I hope that your tests went well. I will email you personally to set up our first meeting. Steven
