Another talk Compass: integrated site Search

Some time ago has written an article about Compass, I believe that we have a certain understanding of the compass

Since the most recent project involves site search and is based on the JPA annotation form and has been on the web for a long time, there are few examples of JPA integration compass, some of which are xml-based, and very few based on annotations, There is no way only to Compass's official website download English documents themselves research, spent the afternoon to debug out, integrated into the project!

Here to share with you, I hope you can take some detours less!

1. Go to the official website to download the Compass jar package, I use the 2.1 version
