I've noticed that several times, when I start typing a search term into Chrome, the suggestions presented are terms already in one of the tabs I have open. For example, if I have "We didn't start the fire" playing in Grooveshark, putting
we didn't into the search box immediately shows
we didn't start the fire as the first suggestion. However, going to the Google homepage in incognito mode,
we didn't gives me
we didn't dybak as the first suggestion.
This isn't bulletproof, I suspect that the results only adapt to the content in the other tabs/windows if the term is already in the suggestion list.
The question is, does Chrome do this, and if so, where is this documented?
