New Changes Effected Search Facility?

Hi has anyone noticed that when searching, the results are not as accurate.  i just searched just now for an email address and it could not find it but only found it when i searched for the part AFTER the @ sign.

I find this a bit of an issue as there are some accounts that i just cannot find.  i have emailed support in the last two days but they seem to think the new changes have made it better and faster.  i think that it's opposite and i do not trust the search results.

What's everyone else's take on this.
