Try to reduce search criteria to actual part numbers.
google search for: [color=maroon]max7219 site:forum.arduino.cc[/color] has about ten times as many results as
but what if I want to search within a particular forum Header like
"Arduino Forum> Using Arduino> Project Guidance "
WHy is there not a search option so I can search within that particular topic instead of having to go through a million posts? This is a basic function of any other forum I've been in on any other web site.
Two words enclosed in seperate quotes often gets you pretty much in the ballpark
eg. "uno" "troubleshooting" site:https://forum.arduino.cc.
That should for all intents put most of the results for UNO and in most cases seperate the troubleshooting section from a lot of the crud..
Add a year or month or user name and get even closer if you want.
