Hi Hexhead, yes. The common question view branch (running on this site) has "search drilldown" mode, which includes tags, search query and authors.
The main deficiency is that there is no full text search on this branch (and this site). When I fix that in a couple of days, and make some adjustments to the search state manager - will merge onto the master.
Try combining it with text query too - just enter something in search and click search button, don't be rough though :) only title search.
If you get stuck in the search - click the logo.
Finally - try searching some phrase, then click "ask a question".
To get authors - currently you have to click on the "users tags" tag listing in the user profile. You can also start with a url like this one: http://askbot.org/meta/questions/?author=5 and then add/remove tags and search query.
In all it took me about two days to build the mechanism and connect it to the UI.
The relevant parts are:
/forum/search/state_manager.py
- function
forum.views.readers.questions
/forum/middleware/view_log.py
Also I've changed templates a bit.
