using community search, sites getting bigger, search has to get better

suggestions to try to make the searching of the community better, more relevent

I've been searching within the community for an article about troubleshoting SQL's working out how efficient they are, and how to look inside the system for other SLQ's that we used but may be inefficient,  (still haven't found it, and getting frustrated)

In this instance, after many guesses, I tried

sql "how to" analyze plan tutorial efficiency inefficient troubleshooting highest

I know I've seen the article about this very subject, but it's getting darned hard to find things in the community.

I'm guessing what to search for I know an article exists, and its not a question.

so what about some better filtering of results.

based upon some of  google's search tools, what about

• the ability to only show the main line(s) of the thread ie ignore the entries found that are the same thread, just further down the page of the thread
• the ability to search only on articles for instance, ie not questions, not replies, perhaps tutorials etc
• the ability to narrow the search and even perhaps tickboxes for the tags ie "its not healthshare, not atelier etc
• the ability to narrow down the results by date range (I know it's not a recent thread)
• the ability to search within the search results themselves.
• the ability to sort the result in "date order" (or reversed)

I'm sure there's other suggestions.

by the way, I never did find the article, so if anyone can point to it, that would also help  ;-)
