I have several times used the search function to see if someone has previously asked a question I am interested in, with no positive result. I then start asking my question and then very quickly the suggested 'Questions that may already have your answer' finds more or less the answers I was looking for.
This tool seems really well implemented, I like that it keeps updating as you type so you can see instantly the different results obtained by changing words (useful for me since I come from a field that uses some non-standard terminology so I'm always fishing for the correct term).
I guess my question is why is the search function so clunky in comparison? I've simply given up using search and now launch straight into asking a question, even when I'm sure the question exists somewhere, just because it is easier to find answers that way.
