Oracle Database - Remedy ARS

Hi,

We currently use ARS with an informix database. We've been told that switching to Oracle offers serveral benefits, the primary one being full text, case insensitive searches. Informix does not support case-insensitive search, and we are looking for a solution that does.

If anyone knows for sure that Oracle will provide this, or, if not Oracle then which Database? Any links, sites, docs, personal observations, etc would be great.

Thanks in advance,
