yes i noticed this as well. sometimes i don't get anything AT ALL recent when i search. is there any way to reconfigure this to show more recent posts as well? for example, i recently searched on "rolling" and nothing came up so i posted. then i was pointed to a recent sticky posted in the last few months that was exactly what i was looking for, even entitled "encouraging rolling". i didn't show up in any of the search results and i went through every page.
