Solutions search is not providing results when searching with multiple words unless they are the first words

Solutions search is not providing results when searching with multiple words unless they are the first words

Situation: We created a Solution with the following title: 
 
Exception Error (EE) selecting allergy from PIF
 
Problem: Enter "selecting allergy" in the search box and you don't get a result.
 
If you select "allergy" or "selecting" you do get a response.
 
If you select "Exception Error" you do get a response.
 
Is this the expected behavior?  Shouldn't it give me a result regardless of the position of the words within the string?
