I created a suggestion: QTWEBSITE-148 [bugreports.qt.nokia.com]
An enhanced search for the QtDevNet would be nice. Up to now I can look for tags or content. The content is always searched by main topic (forum, wiki, …).
What I would suggest is give more possibilities for the search: – search in one sub forum (e.g. beta, desktop, …) – enable search options (all words, one word, and, or, …)
This would help searching the dev net for needed content.
Some of those use-cases can be solved with the advanced forum search: http://developer.qt.nokia.com/forums/search (link on the main forum page)
The main site search (http://developer.qt.nokia.com/search, or top right) is by Google, so normal Google tricks work. http://www.google.com/support/websearch/bin/answer.py?hl=en&answer=136861
Tag search currently doesn’t support any AND OR NOT notation. We’re considering making that though, more here: http://bugreports.qt.nokia.com/browse/QTWEBSITE-135
