Take a Guess

The word "trawling" has come to be used in a number of non-fishing contexts, usually meaning indiscriminate collection with the intent of picking out the useful bits. For instance, in law enforcement it may refer to collecting large records of telephone calls hoping to find calls made by suspects. The word "trawling" occurs frequently in general literature and is used to mean searching through literature for information more often than it means catching fish.
