Bill Don't you need to translate the BLOB content into indexable text before you index it? A simple transliteration of hex values is no help; you need something that would convert the enclosed encoded Word or PDF into real words. - PDF to text - there are some solutions out there (eg PDFbox<http://www.pdfbox.org/>- an OSS java toolkit; found by Google, no idea if it really works). - Word to text - you could try eg Apache POI <http://poi.apache.org/>(same reservations, and looks like old Word formats may be poorly served). Obviously this will be much easier once you get to Office Open XML file formats - you can just take the XML and dump the text without markup into your CLOB. - In both cases, you'd build a BLOB-to-CLOB converter using a Java stored proc. Once you have indexed the text representation, you can of course discard it (or save some/all of it for preview purposes...)
