Since Lucene uses virtual "files" to store its index, you have to use long binary data types with databases to store them. It seems like each database uses these data types quite differently. (Actually, it was quite difficult to write that OracleDirectory because of Oracle's BLOB implementation.) -- Maik Schreiber IQ Computing - http://www.iq-computing.de mailto: info@iq-computing.de
