Finally! 
One thing that has come to light recently is that the username (if specified) needs to be all lowercase (even if the actual username has uppercase letters) for the search to work correctly.

This is fixed now. You can type Peter or peter or PETER or even PeTeR and you’ll get the same results. What you search for is case insensitive except for boolean operators like AND or OR. So:
headset AND adapter
and
headset AND Adapter
will return the same results. However:
headset and adapter
will return something quite different, because it will look for any of those words, whereas with AND it will look for a post that contains both those words. It actually won’t look for the word ‘and’ either way because it’s one of a small number of words, like “it”, “the”, “he” etc. which are excluded from searches.
