When I search for a term like "formation water", preview returns everything starting with formation and not the term "formation water". How can I search for a phrase in Preview?
Just like you would with a Google search, use the double quotes operator to tell Preview the result must be an exact match.
In your case, for example, typing "formation water" should yield the desired result.
