Need multiple options in profile fields for member search

[Sovereign Grace Singles]

Though profile fields allow multiple selection of options multiple selections cannot be selected in the member search engine. 

For example,

Profile field options:

Country:
America
Eu
Uk
Etc

In the member search when searching that profile field I should be able to ck both EU and UK and have the results turn up.
