Answer 1

If I understand you correctly, you have two questions:

1. Can I store a project id in Lucene and use it for further searches? Yes, you can. This is a common practice.
2. Can I use this project id to search Lucene for project meta data? Yes, you can. I do not know if this is a good idea. It depends on the frequency of your meta data updates and your access pattern. If the meta data is relatively static, and you only access it by id, Lucene may be a good place to store it. Otherwise, you can use the project id as a primary key to a database table, which could be a better fit.
