Query: DOES NOT WORK ON KINDLE FIRE

In Kindle Fire, there is no search function that allows you to search for a single word and its definition. The only search is the Fire built-in one that looks for the word in every place it appears in the book. Search for "liquid" took 4 mins 37 second and returned 134 instances of the word. Amazon confirmed there is no search feature for kindle fire only the e-ink family. They also confirmed that there is no dictionary available for Fire that has this feature.I asked for and received a refund.
