Workspace: adjust search relevance or make exact match also available

When I search "eVar1", I get all kinds of eVars where there is just number 1 included. In ideal situation, search result would show first "eVar1" and not "eVar11" or "eVar19" etc. If I look "eVar25" I get 2 results "eVar25" and "eVar52". So search should interpret exact match only, or again we should option to use exact search or wider search. Or ideal situation would be that search results would be divided to two parts:

exact match:
eVar1

(empty space)

Contains match:
eVar19
eVar11
eVar1 and so on.
