[Description] Relevancy scores are, in part, determined by the number of occurrences of a word. This algorithm can sometimes lead to unexpected results. For example, while you might expect "laptop" to be most relevant to Computers category, the relevancy score is higher in "Sporting Goods" because the word "laptop" occurs there more often, for example, in phrases such as "laptop bag." [Impact] Do not use ItemSearch requests sorted by relevancy. [Issue] 
Relevancy score values are sometimes unexpected.
