My wife Tasneem and sweet little daughter Munira were patient throughout my writing adventure, and I want to thank them for giving me tremendous support and quiet space to work at home. I would also like to thank my mother for her moral support.

My inspiration was Dr. Tarique Sani, CTO of SANIsoft, who is my employer, mentor, and guru. I would like to thank him for his support and exchange of technical know-how. I would also like to thank my colleagues at SANIsoft who encouraged me in my endeavor.

I would also like to thank all the reviewers and editors who worked patiently with me. A special thanks to Aaron Rosario who worked sleepless nights during the final editing phase.

Richard Phillips of Utilitas Knowledge Management Limited, London, introduced me to Sphinx while I was working on one of his projects in 2009. He deserves special thanks and acknowledgment.

Last, but not the least; I would like to thank my brother who has been an inspiration all my life.
