TREX

I am new to TREX.

We are using content management server to store our documents.

The docuemnts are searched using enterprise protal. I have got following questions:

1. Is there any step by step guide to configure TREX.

2. Is there any standard way TREX can filter the public and private document. When a user search for a document from the portal, only the public document should appear. (Public or private is the custom metadata for a document).

3. Also how to use TREX ABAP API. My requirement is For eg, when a user type a keyword 'ABC' to search for documents, the TREX return only those documents

where content having 'ABC' and attribute1 is 'XYZ' and attribut2 is 'DEF' .

Thanks a lot for you help in advance.
