No partial matches probably related to how they index emails to save on space, I found it annoying once or twice too but not a big deal. As for the rest - well, I don't really want it to 'fix' my typos(especially since I'm bilingual) and I actually like indexing of email attachments, I often looked for products I bought and found them through invoice attachments. I like how fast it is though, I instantly get results from gigabytes of old emails, I can forgive lack of partial matches here.
