Hi Catherine,

My recollection is that Quick Search does not support boolean operators, only Advanced Search.

What Quick Search does is drop your search term into your selected search types as the value. 

As an example, imagine I have two fields:

1. FirstName
2. LastName

and a document with field values of:

1. FirstName: "Samuel"
2. LastName: "Carson"

a Quick Search on All Fields with the search term "Samuel Carson" will not return this document because:

1. FirstName: "Samuel" does not match %(SearchTerm): "Samuel Carson"
2. FirstName: "Carson" does not match %(SearchTerm):"Samuel Carson"

By default, Quick Search will find partial matches when the Search Term is a substring of the value, but not when it's larger.

I.e., if I have field FullName: "Samuel Carson", a Quick Search for either "Samuel" or "Carson" will hit a partial match and return the result, but a search for "Samuel Carson" will not hit a partial match on the FirstName: "Samuel" field.
