Hi,
If you know the EXACT title of the account you could type it without any * and the search result provides you the account/s. If you want to type a part of the title then you should use * before the phrase. Example: Account name= "ABCD EFGH IJK".
If you search "abc" or "ijk" the result is none! If you search "ABCD EFGH IJK" you have one result. If you search "*abc" or "*efg" you have one result.
AFAIK there is no way to eliminate this behavior.
