[eclipse.org-eclipsecon-program-committee] Can SQL be clarified?

[David M Williams <david_williams@xxxxxxxxxx>]

I've tried some "search queries"
that don't seem to work for me ... and wondering if something in the system
has changed ... or, if I'm just ignorant of SQL (or both :) 

For example, 

talktag~'JavaEE' order by type

returns a result, but not ordered by
type

(talktag~'JavaEE') and type ~ 'long'

returns "sql error" message.


More in line with my ignorance, I've
tried to narrow search in following ways, but none seem to work: 

(talktag~'JavaEE') and (talktag ~ 'tools')


talktag IN ('JavaEE', 'Tools')

Are these issue bugs? Or inherent limitations?
