Math search capabilities are expected to be widely available in thenear future. A key question is what roles can or should math searchplay in mathematics. Besides the fundamental role of findinginformation, it will be argued in this talk that math search can helpadvance and manage mathematical knowledge. After presenting anddemonstrating some of the state-of-the-art features of math search, wewill focus on how math search can help mathematicians advance andmanage MK, and discuss the steps that will have to be taken to fulfillthose roles. In particular, two areas will be emphasized. The first isthe use of math search for discovering similarities and associationsbetween mathematical patterns/structures, and the application of thatto helping mathematicians with proof development and with thereduction of new problems to known problems. The second is mathmetadata, which math search will surely encourage and benefit from,and which will be pivotal to mathematical knowledge management.
