Can any one let me know how compass is retrieving data from database.I have few doubts as i came across the evaluation of compass in our project as given below
1) Does compass index data in pojo's or from database?
2) If it index the data from pojos, can we index data stored in ebj's?
3) How compass is retrieving data ?
3. a) Is it actually use a reference from the index to link to database ?
3. b) Does compass make use of any database specific search engine (eg) oracle text ) to retrieve data
4) If we need compass to search a 1000 table database with gibabytes of informations, Do we need to create those 1000 pojos in our application ?

We are using hibernate for object relational mapping in our application

What if my application wants to search the database of another application?

More precisely I need to integrate my search application with my Enterprise application only to search for informations availabe in that, were the Enterprise application may or may not have ORM

At the end of the day, you can do your indexing yourself. Compass comes with support for what is called RSEM, which means you don't have to use OSEM to store things in the index.

If you are using OSEM with Hibernate, then it is very simple to index your database. If you are using plain Jdbc, then you can use RSEM (or OSEM, if you have simple mappings already built).
