Sometimes you get tired of the search limits set by the forum software. It might be faster to use Google: type "site:soft.com.sg" followed by the keywords you are searching for in Google.
You're welcome. Google has 2 limitations: it takes at least a few minutes to hours to index the newest posts, and it wrongly detects some dates due to the US English format (01-07 which is 1st July to us, becomes 7th Jan to Google). Other than that, you can even use it to search specific categories, like typing "site:soft.com.sg/forum/guitar-buy-sell/ fender" will search for all the Fenders in the guitar buy & sell only (no amps etc).
