Googler, Jem, started a thread at Google Web Search Help asking the forum members to list out some of their favorite search features.
The ones listed so far include:
My favorite queries are mostly site: command related, when I want to find content on specific web sites. I do however greatly miss inquisitor, the search toolbar, that allows me to save advanced search queries, so I can run them quickly. Snow Leopard totally removed the ability to run these types of plugins in Safari.
What is your favorite search feature?
