I have just recently converted from using Windows Live Mail for my email to Gmail. Mainly because there was not an easy way to sync my contacts between WLM and my Android smartphone. Syncing is much better now, but the system differences is taking some getting used to. I notice when I am using Gmail and search for a past email, many times Gmail doesn't find it. I try it searching by contact name, by contact email address, and by subject. Of course, I can scroll back through my old emails and find it manually, but it is frustrating that Gmail cannot spot it quickly. It seems to have the most trouble when I am trying to find a SENT email. Sometimes, one I just sent yesterday. I click on the "Sent Mail" folder and the search box shows "in:sent". I type the info and nothing is found. I have tried it backspacing over the "in:sent", and with leaving the "in:sent" in place before my info. Neither way seems to help. Is there a setting I am missing?
