Gever Note

I continue to have problems with exact searches. For example. I just searched for "AT&T". Instead of finding the half a dozen notes pertaining to AT&T, I get hundreds of notes that contain "at" anywhere in the note. I searched for "Van", and I get a ton of results from words that include van anywhere in the word like ,"advance," "vance," to any notes that simply have a "V" in it. And then I have a bunch that don't contain "van" or "v" at all, and more that misidentify hand written words as "van" when it's not even close. I thought the quotes meant it would search for exactly what's inside the quotation marks in it's entirety. This is really driving me crazy. Help!
