Agatha, Hercule, Mummy and Me - Negative Search



http://ow.ly/7zaM3

An article b Craig Ball, Esq. on his blog Ball in Your Court.

This article discusses the concept of "negative search".  The author writes, "Though similar in certain respects, negative search is not the same as using Boolean constructs to exclude noise hits. Boolean constructs are quite effective when artfully composed, but can be challenging to frame and tricky to execute. Negative search doesn’t restrict queries in the way Boolean constructs do. Instead, negative search finds all documents containing terms deemed highly unlikely to occur within responsive documents, like “birthday cake,” “fantasy football” or “bridal shower.” These are then excluded from review. Clearly, negative search terms must be chosen wisely and tested carefully against representative samples of the collection before broad deployment."
