This is a paste from a message that Jillycakes sent me.
Usually the best way to find an exact term like that is to do this:
Click on "Advanced Search"
Type your keyword into the "Search by Keyword" box.
Use the drop menu to switch the search parameters from "Search Entire Posts" to "Search Titles Only."
I tried this using Google Trends and found a bunch...you'll miss out on some threads where Google Trends randomly came up, but searching that way will help you find all the threads that were started about Google Trends.
As far as other searching tips, I'd also recommend searching by "User Name" when you find someone who does what you're interested in doing, or that you notice always says helpful things. Searching by user name lets you dig through their posts for further learning.
I hope that this information helps others.
