Stop using google search

I discovered today that not all packages have been indexed by Google. For
example the 64-bit "gcc-core" which provides "gcc.exe"

http://cygwin.com/packages/x86_64/gcc-core

This search

http://google.com/search?q=%22installed+binaries%22+%22usr%2Fbin%2Fgcc.exe%22+x86_64

currently only yields the "gcc-debuginfo" package.
