Hi, I am new to the community and is interested in learning about Lucene architecture and capabilities. Before diving into the code directly I am looking for some suggestion/pointers on how to start about it. Probably something which can give a high level overview and talk about few core concepts in depth, that will help to grasp code easily. I have some SQL background, and wanted to compare/understand how Lucene does search query planning (parsing/generating AST, etc) and if there is any concept of creating statistics about the data being indexed. Please advice.
Thanks, Sorabh
