There's plenty of work to do to improve the way that Joomla works with databases. We need database experts who can look at optimising queries, improving the data model and making Joomla work across multiple databases. If you are a database junkie and you'd like to help then contact Omar Ramos.
Improving Joomla search is something that has been requested for a long time as the native Joomla search function leaves a lot to be desired. Because we want to move towards a unified content model it is really important that we address search as part of that. Many of the issues have already been successfully addressed by JXtended with their Finder component. However, Finder will only work with Joomla 1.5.
