Connecting to TREX without KM

Hello,

We are implementing KM and TREX in it in owr company, but also would like to have another self build application that will connect to trex and run searches getting results from it.

Can we do this ? with KM jars/XML documents/web services/ etc... (I'm asking this as I saw in earlier posts that the TREX API is not released)

also we need TREX to index an Oracle database, it that possible ? if it is, where can I find documentation on how to do this ?

Thank you,

Carmit.
