How to make an OR search in Lime CRM?

To do an OR search means that you are searching for something that contains a value OR another value. 

For example, to search for companies that are either located in Lund OR Copenhagen you need to type "Lund OR Copenhagen" while using the fast filter.

Note that you need to use upper case letters in order for lime to understand that you are not searching for the word "or".

Standard is to make an AND search.
