如何在Solr Index中添加Java entites？

Question

I'm new to solr. I've gone through a couple of blogs on solr integration into a web project. In my current project, the different java entities are stored in the solr index as space separated serialized string. Like, firstname + " " + lastname + " " + email....and so on. All the disparate entities are stored like this with classname_primaryId as the unique key. Is this the standard way of storing the different entities in solr? How should I go about it? Can I keep these entities separately in solr? Any guidance/help is appreciated. I'm already short on time!!!!

Solr is a document search engine, so you should think about your data in those terms.

If you want to make the entities searchable, I believe that the best way would be to serialize the Java entities into documents (objects represented in JSON), and then add specialized fields (such as a copyField that contains data from all other fields that you want to search when field name is not specified) on top of that. You don't need to do the space separated representation at your application side, Solr handles that automatically when you use a copyField in the schema.

In this way you have the ability to search on per field basis, and when required search on all fields at once by targetting the copy field.
