It is called being "a search function nazi", and it is in the same league like "manual nazi" (the guy who likes replaying with "RTFM").
I.e. ED (Eagle Dynamics) forum is full of them, and I consider it to be a good thing because of technical nature of that forum. Most things are analyzed there comprehensively in separate threads, and no one wants to repeat the same over and over again, especially if that requires multiple walls of text. In addition, encouraging use of search function eventually leads to better studying skills.
