easysocial search too accurate

hey guys, looks like the easysocial search is too accurate and therefore not really handy for the users.
given the example of 2 (of course already correct indexed) users named mark and marko to replicate:

prob1:
when you type, for example into the easysocial search module, "mar" (the first 3 letters of both names) you'd expect that both results come up - in fact: none of them are shown
if you expand this to "mark" you'd expect the same - mark and marko should show up - but now only mark (which is matching 100%) is showing up.
to get to the result marko you would have to enter the whole name again, that's the only way to see this user.

prob2:
while we're at our last search (marko) we stay in the search box and remove the last letter "o" so that in fact we now have "mark" in the box. funny though now even mark is not displayed, you don't get any results at all. looks like you have to actively type something in order for the search to work.. so in fact you would need to go back from "marko" to "mar" and then add "k" and at that point the search starts working. that's not very intuitive and I guess many endusers on the site won't get that ^^
