Using quotes and limting the results to this site in Google can be very effective. Try copying and pasting the following into the Google search box on the Google main page, WITH the quotes:
"j pickup" site:talkbass.com
Also try the same for "MM bass", "P bass" or "SX bass".
Adding other terms outside the quotes to limit resluts further whilst not searching for an exact string of characters works well too. Try these two, noting the different position of the quotes.
"P bass nitro finish" site:talkbass.com
"P bass" nitro finish site:talkbass.com
Use of the minus sign to exclude terms can also be handy:
"P bass" nitro finish site:talkbass.com -vintage
