I tend to use google for searching forums as forum search functions aren't particularly as good, especially some forum software where you can't seem to search for phrases, only getting results for each individual word in any context!
Maybe people don't know this google search method? You use the "site" function and a search looks like this:
Apples and pairs site:theartofsound.net
Note that there's no space between "site", ":" or the domain name.
That will search any page in the artofsound.net domain (including any subdomains, though for theartofsound.net there is only the "www" subdomain) for the words "apples", "and", and "pairs" .
Because it's Google, you can then use other boolean terms and characters. So to search for the whole phrase "Apple and Pairs" on AOS, you type:
"Apple and Pairs" site:theartofsound.net
or you want "apple" and "pairs" on the same page you can use:
apple NEAR pairs site:theartofsound.net
or
apple AND pairs site:theartofsound.net
etc etc ect
(sorry if this is teaching you to suck eggs with google!).
So there should never really be any problem searching any website or forum, just use google instead of the forum's own search facilities.
