prad_intel,

In practice would this work?
This would not be a problem if people used the site properly :)
Your node Sample of Win32::GuiTest needed for this was titled "software upgrade for mobile phone" before you changed it, and the question several times, after people had replied to it.
How would your proposed system deal with this?

Matches you would have been given based on keywords of your title alone would not have helped you, and as you updated the question several times (mostly at the request of various monks, to provide a structure and explain what you were actually trying to do) I dont see how this feature would have helped you.

I for one dont think that it is too much to ask people to Super Search before posting.
But as I have attempted to illustrate, the site is dependant on people using it properly, creating nodes which are well structured and contain information relevant to what the poster is trying to achieve.
As far as downvoting goes have, a read at Why downvote nodes without commenting on them?.
