I'm not sure you understand which "search" I am talking about.
If I go to Advanced Search and search for a specific ticker symbol in public messages I get what I need.
It's when I go to the Search box at the top of this page and put in a ticker and use the drop down box to search public messages. The last message is from 3/8 and there were more on this ticker yesterday.
That's one of the best features on IHUB and probably the one I use most to see who is talking about a particular stock. It's all about saving steps.
