Adding enhanced search for QtDevNet

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.
