You could also look into the advanced indexing of OMNIDEX, which will give you instant keyword access to your VARCHAR2(4000) field, with superior performance to Intermedia Text. See
http://www.disc.com/keyword.html for details on keyword indexing and http://www.disc.com/prllnl.html for a customer who chose OMNIDEX over Intermedia. Or contact me for more information.
