1. Is the current search function sufficient? Are you able to find what you are looking for?
-- Most of the times, yes.
2. What function do you think need to be added to the search function?
-- Perhaps a regex seach option? But I'm really pushing it here since I doubt many would use it.
3. Do you use the advanced search function more OR the quick search bar at the top left of every page? Any reason for your choice?
-- I use the quick search bar more, simply because I have no need for the advanced search most of the time.
4. Is there anyway to further improve the quick search bar at the top left of the page sufficient?
-- Not really, no. It's got all it needs.
5. Are you aware that you can use wildcard search by putting * at the end of your search criteria to improve your results?
-- I was not aware of that. I am now, however.
6. Please try this method of searching and feedback
a. Go to http://www.google.com
b. Type: site:mobilism.org (SearchTermsHere) Example: site:mobilism.org Battery Monitor Widget Pro
c. Do you like the search result obtained?
d. Would you like the site search function to be similar to it
-- I've used that way to search before, mainly on the phone before the market application when I couldn't bother logging in. It definitely works, but I wouldn't bang my head about it too much.
7. Any other opinion that you would like to give?
-- Not at the moment, no.
