Hi, All As many of you may or may NOT notice that: tahiti site(tahiti.oracle.com) has been redirect to docs.oracle.com . Tahiti offer a simple and easy search interface. One can do a search within 3 steps(typing keyword, press search button, choose document version). Now, in my opinion, it's very less efficiency: First, it's it use a lot of step for doing a basic search on Oracle database knowlegde. Second, from direct link on search pages from different version: 10g R2: http://www.oracle.com/pls/db102/homepage 11g R2: http://docs.oracle.com/cd/E11882_01/index.htm 12c R1: http://docs.oracle.com/database/121/index.htm from above 3 links, no easy rules for user to remember. And BTW, I think Oracle should give customers a list of what previous doc bug has fixed and when the new doc released should info customers. Best Regards, Milo
